1. be known as a sexist or as a racist
Racist. Somehow it seems like the least stupid of two stupids. If that's even a thing. EDIT: I found out why: in the right ethnic community you can still be comfortable vs sexists can't hide from an entire gender XD
2. be topless or be pantless (underwear allowed)
If I can have underwear, pantless. It's less revealing.
3. have sex 10 times a day or once a year
Once a year. I can still jerk off!
4. give a nude pic to anyone asking for it or have no sex
Give a nude pic. I mean if it's an obligation, I'd have no shame in it! I guess I'd be a trans curio and it would be educational.
5. wear a chastity belt or go commando every day
Commando of course! Are you suggesting I trade my orgasms for a pair of boxers nobody would even see?
6. have only anal sex or only oral sex (no standard sex at all)
Only anal, because as frustrating as it is for my pussy at least I get penetration. I can still jerk my junk.
7. be a sex slave or have no sex
If we're talking real life sex slave, "have no sex". I wouldn't want to be any type of slave. If we're talking kink as in "always be a complete sub"... I don't know... I'm really tempted to pick "sex slave"! :P
8. wear a butt plug or be restrained while sleeping
I hate both 
the restraints I guess, if they're light? Not sure.
9. wear a chastity belt or give oral to someone you don't know once per night
Give oral, but they better be clean of filth and diseases.
10. be a girl with a penis or a boy with a vagina
Ha, ha. I already got that picked for me don't I? Well I really can't imagine being happy as a girl in any situation so I'll stay as I am.
