I am in a 3 year long distance relationship with my boyfriend and since 6 months I have been having this weird fantasy to watch my boyfriend having sex with another woman. I have told him about this and asked him to make this real and send me a video of him like this. He told that he is afraid to loose me and he told we can use this fantasy just in thoughts but in reality he has the fear that I ll leave him. He seems excited sometimes to do this but due to the fear of loosing me he is scared. But I am sure that this is just a sexual fantasy and won't ruin my relationship and we are getting married in 2017.So how to convince him to fulfill my weird fantasy. I need suggestions. Please help.
You're better off waiting to fulfill your fantasy in person anyway, if you still feel that way in the future. Fantasies are pretty much always better in theory than practice.
Even if he wanted to fulfill your fantasy, it isn't easy. He has to find a woman who'll want to have sex with him and who'll agree to do the video and send the video to you. The likelihood of that happening is thin, very thin.
