NSFW and Physical detail
Sensory Details
Scent: Tony, well, he’s got several layers when it comes to scent, so we’ll start at the bottom and work our way up.
Tony always has an underlying tone of ozone to him. It’s very faint and sharply metallic, but this is from the arc reactor. If it’s off, for some god awful reason, this scent doesn’t vanish, though the coconut tinge over the whole thing would. He likes to use tea tree shampoo and orange-mint soap.
Tony has two stages after this, Public face and Private face.
If he’s been in Public and has been dealing with the media, politics, or specific business people, he will be wearing cologne. It will be low-key, woody, and he’d almost definitely have the scent of makeup on him. He prefers the ones which are more mineral based on his skin, so it’s probably going to have that kind of tang. In situations where it’s viable, and happened before the birthday of 2010, he’s probably had a drink, and Scotch being his favorite makes it the most likely scent. However, champagne is equally likely. If it’s after 2010 he will have switched to tea and bubbly juice that passes, so please keep this in mind.
If he’s been in Private, working in his shop, sparring, or just not caring, he’ll probably have the sharp clear scent of metal and engine grease on him. Even just lingering around in his workshop is usually enough for this, because Dum-E will cozy up to him when Tony is doing nothing more than just tinkering with holograms.
Please note in any situations with a reactor before his Badassium one (he will not change the name and you cannot make him) in 2011 will have instead of coconut a much more sour note to his scent that is far less pleasant.
Sounds: Tony chatters, so his baseline sounds are probably a lot more than is readily obvious.
First up, after the events of Christmas following the Avengers, with the Mandarin, Tony’s chest sounds different than it did before. Before the Mandarin and his following surgery, there was a subtle, persistent grind of bone on metal because his ribs were grinding against the casing of his reactor. Afterward, this is gone, as his bones were secured into the new casing during the surgery.
Tony always takes slow, shallow breaths. It’s not obvious, because he takes care that they’re even, but he has decreased lung capacity, and this will always impact his ability to breathe. When he’s distressed or has been very active, he still does his level best to make completely sure to keep a grip on his breathing, even when it’s fast, because otherwise, he won’t get enough air.
His heart rate, ever since Afghanistan, has always been faster than normal.
The reactor, no matter the model, Hums. It’s a soft, low noise and is a deep enough pitch that it doesn’t grate while being quiet enough most people have to put their cheek on it to even notice.
Taste: Tony is way too involved with his technology, and because of this, there is always the faintest metallic taste on his skin. It’s not so strong as to be unpleasant and is cleaner because of his tendency toward high-grade materials.
It should also be noted that there is no escaping his kisses tasting like coconut. He just does. If it’s before his last reactor, you’re more likely to get the tang of alcohol.
Feel: Tony has two things that really set him apart.
First, his skin is a little softer than the average person, because he’s always had access to a hell of a lot of pampering. This doesn’t mean he doesn’t have callouses, because he does, and not just a few either. It just means that how they’re placed means they’re not usually noticed by visual cues.
Tony has a higher than normal body temperature. This wasn’t true before Afghanistan, but his body reacted to the constant energy cycling of the reactor by bringing his temperature up. He’s since gotten used to it, and only ever notices when someone comments, which is almost never. This has also resulted in him perpetually having warm hands even in the dead of winter, so he doesn’t bother with gloves for practical reasons.
Sight: Tony is 5′9″ tall, with dark brown, almost black hair, and light brown eyes. Just so there’s no confusion.
He’s also got hella muscles because he can and does manually lift heavy pieces of technology himself on a regular basis. Sure, he can be patient, but he honestly doesn’t usually bother if it’s something he can move himself. His hair has a tendency to curl when it gets more than a couple inches long, which most people never see.
His scars are often expertly concealed, and mostly stay hidden under his clothes in any case. No one will ever accuse Tony of not being fit, at the very least.
Other Abilities: One side effect of the element Tony created is that it interferes with magic. If applied directly to it, it washes off harmlessly, dispersing, but if bypassed, the effects will have a definite diminishing return with each successive application.
It should be noted that mind readers would probably have a slightly different time tracking Tony’s thought processes than normal because he tends to run on multiple mental paths at once. This means that he might be thinking of some project on one level, a different project on the next while contemplating his breakfast options, all the while his attention might be on something else entirely.
Neither of these makes him impervious to mental attack, but it certainly means that things are a little odd for the people doing it.
NSFW Sexually Oriented Details
Tony has slept with many, many people in his life. He cannot number them for you, though he can easily say that he’s been with more women than men. He can also say he’s always done his level best to please them, no matter what, once he had them because he really does like making sure his partners are satisfied when they leave him or he leaves them.
Tony only shares a bed with people he trusts overnight if he’s sleeping. If he doesn’t trust you, once he’s done, he may linger, but he won’t sleep. Waking up alone for one night stands was practically the norm. However, not sleeping doesn’t mean not touching, and he is highly prone to after sex cuddles if he hasn’t been struck by inspiration mid-coitus. Alternately, if he goes to sleep with you in a platonic sense, trust or not, he’s really not expecting sex come morning.
Speaking of, for Tony, sex is one of those activities that he doesn’t have to think about most of the time. He knows what he’s doing, and he’s content to follow directions. In fact, this is one time where he tends to happily follow directions.
Of course, because his mind is for once not really engaged the same way as it otherwise would be, he’s been known to get suddenly distracted and in his twenties had the unfortunate habit of writing equations all over his partners mid-sex. He’s since learned that his partners don’t usually like that.
Which means that these days he’ll satisfy his partner ASAP and lunge for a tablet or paper or something instead. Unless it’s another scientist because he’s pretty sure they wouldn’t mind. Non-scientists, well, they’d have to ??? at him before it’d come up, probably.
Tony, after Afghanistan, is not okay having sex in a tub, shower, pool, or any other thing with water in it. He actually used to really enjoy this before Afghanistan, so he’s actually somewhat bitter that the notion now gives him panic attacks.
Similarly, anything that even teases the line of consent issues had better be heavily discussed with lots of safety precautions put in place beforehand. He will never risk someone not being able to say stop or no in some fashion, not even in the middle of some kind of scene someone asked him for.
Playing with sensory deprivation is iffy for similar reasons, though he will not countenance anything that makes him unable to breathe for any reason, though he’s found that collars he’s in control of the tightness for give him no problems.
Sweet talking him. Tony will be flustered and uncomfortable if you come at him with compliments and soft kisses, but he’ll also cave because he’ll want to see where you’ll take it. He’s not very good at accepting these things at face value, and even if he likes it, his uncertainty will usually invoke some degree of sarcasm as he tries to deflect the attention to something more reasonable. It’s been known to be a serious romance killer.
On the other hand, he’s perfectly happy sweet talking someone else and is liable to turn the tables hard and completely overwhelm his partner should they falter in their doing it to him. Or just spring it on them completely unprovoked, this too is a thing he’ll do.
Tony doesn’t like being vulgar to people in bed. He never calls people whores, sluts, worthless, or anything of that nature in bed. It makes him uncomfortable to try doing so on request and it’s one of those things he just can’t bring himself to give someone.
Tony has spent years examining the human body. He knows how to recognize a good reaction from a bad one and is extremely sensitive to kinds of twitches that mean someone liked something. This means he’s really good at making his partners feel good using his touch or mouth alone.
He likes to explore, to revel in his partner, and to learn everything about what they like. This includes, sometimes, seeing how many times he can get someone off in a night if they’re into that.
Tony’s got a nice, average sized cock as a guy, nothing overly large or overly small, without any real lean.
As a lady, she’s got a rather small chest and is more slim and muscled than anything, and has zero problems with this.
He’s got a lovely ass either way.
Tony has rather good endurance, even with him getting older. He bemoans his lost recovery time though, and some nights can only go once, which means he focuses extra hard on the other person if he’s feeling tired. On a good night he can manage up to three, maybe, but the recovery time is sometimes as much as an hour if it happens at all.
Tony’s hands are sensitive to touch, especially along the backs of them, though he notices people almost never touch them in a sexual way. Similarly, his face rarely gets much attention in spite of being another zone he deeply enjoys having attention paid in a sexual way. His jaw, the backs of his thighs, and the base of his spine, by contrast, get absolutely lavished in attention.
The area around the reactor is actually extremely sensitive, but he’s so paranoid about it that it’s hard for him to actually enjoy it.
Foreign languages during sex only turn him on if he can understand them. If he can’t, then he better be totally in control or things might go a little sideways as he tries to figure out how to handle it.
Tony is willing to try anything a partner asks that won’t trigger a panic attack. Unfortunately, the list of what things will do that keeps growing. It’s kind of pissing him off.
Tony likes to watch faces during sex. Seeing bliss on someone, be it body flushing, glazed eyes, or other physical expressions of appreciation, does more for him than hearing a groan or being touched back, in terms of gratification at least.
Tony likes people sticking marks on his skin. Not from one night stands usually, but from lovers? He’ll love having handprints on his hips, or hickeys on his neck, even claw marks down his back. He’ll wear them like badges of victory and regret nothing.
He’d happily return the favor if his partner expressed interest, of course.
Given Tony’s sexual orientation, Asexual, getting him in the mood in the first place is an exercise in care. He’s very reactive, and physical contact is liable to rouse his body, but trying to flirt and throw innuendo at him is unlikely to do a thing for him. If he’s already horny, well, that’s easy, but knowing when that is is all a matter of knowing Tony, so everyone gets a good luck on that one.
Regardless of this, he’s very often willing to attend to someone else’s desires, most especially when he cares about them.
