1. What is your underwear "style" of choce?
This is going to be the most boring possible answer to this question, but here goes anyway: It honestly depends on what else I'm wearing.
Anything that would show a pantyline, I typically go thong (that is, after all, why they were invented). If I'm just going out in jeans to sit in class for three hours, I'm probably going to go with plain ol' cotton briefs (bikini briefs of boyshorts, if that helps those of you trying to visualize).
If I'm dressing "with intent" -- in other words, if I am
planning for someone else to see them or take them off of me -- I'll go a little fancier; silky, lacey, mesh, or whatever depending on my particular mood and the mood I'd like to set for the encounter.
2. How old were you when you had your first sexual experience?
If you're talking about losing my virginity (or, really, anything else actively involving another person): Fourteen.
Go read all about it.
If you're talking about just general sexual experiences, I discovered masturbation -- which I consider a sexual experience -- several years before.
3. What about a potential partner turns you on?
Smiles that you can see sparkling all the way to their eyes. Strong hands and forearms. The ability to so engage me in conversation that I lose track of time.
4. Have you ever played a game which may require you or others to disrobe?
Of course.
(You wanted more of an answer than that? Tough.)
5. Given or received finger scratch marks during sexual activity?
Given? Frequently, yes.
Received? Not so often, but once or twice.
More often, though, after a particularly rough or rowdy session, I find that I have bruises in the shapes of fingertips on my hips.
Bonus: How many times is the most you have ever had sex in a 24 hour period?
A dozen? I don't know.
Typically, if it's one of those kinds of things, I don't break it down into individual times and just count the whole day as "having sex." I mean, otherwise, you have to get all nit-picky about what constitutes "having sex" and what doesn't.
(For example: Do you have to orgasm for it to count, or is just plain penetration good enough? If it's not sex without an orgasm, couldn't it be potentially sex for one partner without it being sex for the other? If it's just penetration, does it have to be continuous penetration? If not, then shouldn't each disengagement, like for changing positions, count seperately? And, how long does he have to be withdrawn for it to count as actual disengagement? Could a prolonged all-the-way-out stroke before putting it back in be one? What if it slips out? Is that a seperate sexual event ... ?)
Honestly, I'd rather not detract from the event by analyzing and disecting it.
