can't get my dick up? fucked a plate raw yesterday (she's on the pill) and my dick wouldn't get hard, i've been with her 4 times so far and not a single time has my dick been like rock hard. i can get it rock hard by myself at home for like a minute max. should i be worred? should i go to the doctor or something? and no, i'm not anxious while i'm fucking her, rather i'm sad and pissed that my dick isn't rock hard.

so is there a quick fix for this? i take zinc etc all supplements
