My boyfriend of 3 years has been very distant the past 6 months. Over the past 2 months we havent had sex at all, the past 6 months, maybe 3 times. We used to have sex 3 times a week at least. Over the past 2 months hes only come on to me twice and that was when i was sleeping and he rubbed up against my bare but again to cum. I haven't gained any weight or changed too much. I have been open when it comes to sex. I'm 5'3", 105lbs. Whats wrong with me?
