My partner whom I love has a fantasy of having sex with me in front of another man and then allowing that man to sleep with me to show him how obedient I am and etc. I love the idea but I am very loyal and not sure how that would effect our relationship especially since it would kill me to see him have sex with someone else. Opinions and advice?

Your concerns are valid, and you should discuss them thoroughly with your partner before making any plans. Some questions to ask might include:

1. Why does he feel that you need to prove how obedient you are?
2. Would this other man be someone you both know or a stranger?
3. Is he willing to lose a friend (if it's someone you know) or you if this turns sour?
4. What about STDs or pregnancy?
5. If this is to be a stranger, where will this take place? In your home? A hotel? A swingers club?
6. Is this going to be a one-time thing or a regular occurrence?
7. If you do it more than once, will it be with the same person or someone new?
8. If it's the same person, is he going to be a part of your relationship or just a booty call?
9. Will your partner want tit-for-tat (to sleep with another woman)?
10. What if you like the other man?
11. What if you don't like the other man?
