hey, I'm 20 years old and almost always masturbate to gay porn and get turned on from seeing fit bodies and male private parts but I never considered myself to be gay cause I was never attracted to a guy in a romantic sense and I had crushes on girls before and I know I like girls but I only have had sexual experience with guys even though I can't think of kissing them or being in a relationship with one. I recently started dating a girl I knew very well and we kiss a lot. I really like her and am starting to have feelings for her and I enjoy kissing with her and I do appreciate a fit woman's body but I know that eventually we'll have to have sex and I'm just terrified of the thought that I won't get turned on in real time and won't get an erection. whenever I masturbate and try to imagine a girl I don't really get hard but when I imagine a guy I do...I don't know what the f**k is wrong with me and I do wanna have sex with my girlfriend but I'm just afraid my body will refuse it...please help I'm really terrified
