I need your help. I've been in a relationship with my boyfriend for four years. We have done some pretty crazy things in our past, but now he wants me to have sex with another guy while he watches. I don't think this is normal. He says it wouldn't bother him if he is there while it happens. I think it makes no sense for a man to want his woman to be with someone else. Why does he want me to do this?

Dear Alison,

It is normal for your boyfriend to have a fantasy about you with someone else. This is a turn-on for many men. What isn't normal is for him to want to carry this fantasy out in real life.

Although it is his fantasy, it is you that will have to sleep with someone else, something you don't seem too keen on doing. It may be a turn-on for him in his mind, but it is a very different thing to see it take place in real life.

There is a very good chance that his fantasy will turn into a problem once it takes place. He may get very jealous after seeing you with another man. It may also take him a long time to get those images out of his head afterwards.

If you don't feel comfortable with this, you should not go through with it. I don't think there is a question of him not loving you -- he has just gotten caught up in his fantasy. The potential consequences of going through with this far outweigh the benefits.
