So I just started dating this guy, we had been talking for a while and we just decided to make it official. Here's the catch. He has this fetish, he likes when his partners have sex with other people because it turns him on. When I asked if he would do the same he said no. So he would be faithful but he wants me to sleep with other people because it turns him on. Personally when I have dated people in the past it's always been monogamous and closed. No sharing involved. But he likes it, for me it's hard to think in of it as just a fetish and not cheating. He says he will get bored sexually if I don't and I don't know what to do. Is it cheating if he honestly wants me to sleep with other people?
