My girlfriend found out she was just a lesbian, not bisexual while she was dating me (M,20) for about 3 years. We had started dating and she said she liked girls and boys but it was 90% girls, 10% boys. She said I was the only one she ever found attractive and got feelings for. We had sex all the time for the first couple years. But early this year around our 3 year mark, she told me that she doesn't find men attractive at all and dislikes most of them. And with that statement went our sex life.

It had been dwindling for a few months prior but it really hit a wall there. So now we don't have sex at all, and if we do it is because she either feels like she has to, or that she is upsetting me if she doesn't because she just isn't into it and it feels like she would want to be anywhere else. And I hate making her feel that way so I don't let her have pity sex with me. We go months without any sexual affection. She doesn't even like me touching her boobs or ass because of how uncomfortable she is.

Other than that, we have a really amazing relationship! We laugh and love everyday and we both feel as if we've been in the honeymoon stage for three years. So we are so happy with each other, but if I was a girl she would be much much more happier. :/
