I pulled together a "Would you rather" sex game for me and my husband from questions I found and some I made up. I thought some other redditors might like it, so here it is. It assumes a gay couple only, but the questions are fairly flexible.

Not really rules, but I'd suggest:

Both partners answer each question, but take turns answering first.

Questions are in random order, so skipping around is irrelevant.

When answering, you also have to say why you picked your answer. For more explicit would you rather questions, please check out the app I made https://apps.apple.com/app/queer-games-for-couples-spicy/id6468250652

1. The two of you go out to dinner and one of you is not allowed to wear underwear. Assuming no one else will know, would you rather it be you or your spouse going commando?
2. One of you says, "Go down on me - now!" Would you rather say that or have it said to you?
3. Would you rather be on top or on the bottom during sex?
4. Would you rather have a 2-minute quickie with orgasm or an hour of naked kissing/teasing/edging with no orgasm?
5. One of you is naked and the other is fully clothed. You have 30 minutes to be extremely physical with each other. Nothing is off limits, except the clothed person can only be touched through their clothing. Would you rather be the one clothed or the one naked?
6. Would you rather have a foursome with another couple or have sex during an orgy with 20 people where you never touch anyone other than your partner?
7. Would you rather your partner make noise during sex or be quiet?
8. You see an extremely attractive naked person through their open window. Not only are they naked, they begin to masturbate. Given the circumstances, if you look away now, you are 100% sure no one will ever know you saw. If you stay to watch to completion, you are fairly certain that no one will know, but there is a small risk. Would you rather stay through the end or leave immediately?
9. For the next 6 months, would you rather have sex according to your normal "go-to" script or have to do something substantially different every time you have sex?
10. Would you rather have your partner guide your hand while giving him a handjob, or guide his hand while he gives you a handjob?
11. Would you rather send explicit texts/emails to your spouse or receive them?
12. For the next year, would you rather have sex once in your bedroom, or as many times as you like, but never in your bedroom and never in the same place twice?
13. Would you rather watch porn with your spouse or read erotic literature to each other?
14. While having sex, one person must narrate and give explicit descriptions of what is happening throughout the encounter. Would you rather be the one talking or listening?
15. Would you rather send explicit pictures of yourself to your spouse or receive pictures from them?
16. You are going to a strip club with your spouse. Would you rather go to a strip club with male or female strippers?
17. After he orgasms from oral sex, he comes up to kiss. Would you rather he pause to wipe up or go straight to making out?
18. Would you rather have sex in the bathroom or in the kitchen?
19. For the next month, he is only allowed to come on your chest, face, back, or butt. Which of the four would you rather, provided you can only pick one?
20. Would you rather make noise during sex or be quiet?
21. You are both naked and turned on. Your spouse touches themself and has a drop of pre-cum or lubricant on his finger. While making eye contact, would you rather he lick it off his own finger or that he put his finger in your mouth to lick it off?
22. You walk in on your partner masturbating. Would you rather he stop or continue to completion with you watching from across the room?
23. The next time you have sex, someone will get spanked. Would you rather be spanked or be the one doing the spanking?
24. You are having sex with your spouse. Would you rather hear him moan or hear him say something like "you feel incredible!"?
25. Would you rather make out for 5 minutes with a member of the same sex while your spouse watches, or watch your spouse make out with a member of their sex for 5 minutes?
26. For the next month, would you rather have sex once a day or just once during the month?
27. Would you rather have sex with the lights on or the lights off?
28. You are having a threesome with your spouse. Would you rather invite a man or a woman to be the third?
29. You have house guests for the next week and have little to no privacy. You're horny, your spouse's office is 5 minutes away, and he has a private office. Would you rather wait a week for sex or swing by now for a quickie in the office?
