I'm a 19 year old male and I have questions and problems. I'm in a relationship with another male and during intercourse I can't orgasm. When I masturbate I can after an hour or more of constant interaction. I also don't pre ejaculate and sometimes even have problems getting an erection. I think I might suffer from anorgasmia but I'm not sure. It's not something that's interfering with out relationship, but on a personal note it DOES feel like there's something wrong with me.. Can anybody help?
