My boyfriend is unable to have sex with me because he has an emotional connection with me and it "feels weird". He is fine to have casual sex with people he has no feelings for (We have an open relationship). It's becoming problematic for me because I don't particularly want to sleep around, I find emotional connection and sex to come hand in hand so it's been difficult to separate the two, and I do have a fairly high sex drive, currently we do it less than once a month. It's probably been around 3 months at this point. My boyfriend says he doesn't know why he feels that way. Has anyone ever heard of or experienced this before? Is there anything we can do to aid the situation?
