Cannot fuck; dick is limp

Why is it that when I try to have sex with a girl, my dick always goes limp? I can masturbate just fine, even to 3D (not actual porn though). I hate this shit. Why does this shit always happen to me? Why must I be sexually divergent? I just want to have some fun. I am tired of anime and video games; I want to get a life, but it seems "normal" life is not suited for me, despite me appearing "normal" to everyone else. Do I just have to let a train run over me and see what happens? It seems inevitable now.

No shit I am a narcissist. What's wrong with that? I wouldn't mind a narcissist girlfriend. In fact I find it hot. Sadly, they never want me, because I appear too normal to them ;__;

I always get the submissive ones, even though I am the one who wants to get kicked in the balls/teeth by an angry tsundere with high heels. No one ever suspects I would let them shit in my mouth and be their fucktoy all day and night.. or maybe they do, and I simply am too ordinary for them. All I want is a psycho bitch in my life :3
