1: Would you rather be tied up and teased or tie someone up and tease them?
Hmm, tied up! Maybe switch
2: You can either cum any time you wish but you have to swallow it all, or you can only cum once a year but you don't have to swallow.
The former, haha! Chasity is boring, to me
3: Be blindfolded and receive oral but you don't know what gender the person is giving it, or being tied up and and fucked but you can't stop whoever it is fucking you
The latter! Literally a win-win, haha!
4: You can have sex with anyone you want, but they are in complete control of all your orgasms and you have to worship them, or you can be worshipped and dominate, but it's whoever wants to fuck you
I would worship till their heart's content! That would be amazing.
5: Worship feet or have your feet worshipped?
Worship feet.
Scenario 1: You're walking home one night on your own when you are suddenly bundled into a van, tied up and taken to a secret location. You're blindfolded and scared. Your captors give you a choice, you can be throat fucked for an hour nonstop and take as much cum as possible and be free, or be used as a slave for 12 hours and be freed
12 hours! Please have this happen to me! 
6: Tied and whipped or tied and have hot wax dripped on you?
Whipped! Wax is scary!
7: Worship a couple (suck his cock to get it ready for her etc) or be tied up and made to watch someone fuck your SO
Worship
8: Eat your own cum or someone else's?
Someone else, if female.
9: Lick cum off someone's feet or snowball them?
Licking off, AND the snowball!
10: Tied up Spread Eagle while a group males and females ejaculate all over you, or tied in doggy style and fucked in the ass by strapons and cocks?
The former. Would love to be covered.
Scenario 2: You've been naughty and cheated on your SO. They've found out and they're pissed! You get given a choice. They'll forgive you if they get to tie you up, put you in chastity and make you watch while they fuck someone else (and you both know it's the best sex they'll ever have), their new lover gets to use you as well but you won't get any pleasure from it. Or, they'll forgive you but you have to violate a limit, get humiliated, and you must deepthroat 5 other guys but once again, you won't be allowed to cum.
The latter. Humiliation for the win!
