Girlfriend has no sex drive
I've been dating this girl for 2 years now and when first started going out we were very sexually active, but since probably about 6 months in the strive on her part has disappeared. I feel horrible about myself because I love her but I'm not sure that she finds me attractive anymore. She tells me otherwise but her lack of wanting me for so long I guess has taken its toll. She's a great girl and she says that she has low libido which I believe is what makes women want sex, and I understand this but can't help feeling the way I do. Is it wrong to feel this way after so long? We have sex probably about once every month and a half to 3 months. Were both still very young I'm 19 and she's 20. And is there anything I can do to help this situation.
