This is kinda difficult for me to talk about, but I think Im losing interest in sex. I am 25 and up until 3 weeks ago, havent had sex in about 2 years. 3 weeks ago, my girlfriend and I were having sex, and I went limp for some unknown reason. I couldnt really keep my mind on sex. I just didnt feel as into it as I should have. Im thinking that going so long without sex has something to do with it, or its just because Im not a very confident person. Im constantly feeling like Im not good enough because I have a below average size penis. I have very low self esteem and Im constantly depressed and stressed out. Also, I rarely ever even feel the urge to masturbate. Im trying to figure out if I should take those pills to increase libido or not. I have no idea what to do. My girlfriend broke up with me last week because I wasnt intimate with her, and that I wasnt showing my love for her. I would appreciate any help anyone could give me. Thanks.
