I'm 17 years old and I have a hard time getting and keeping an erection?

I'm 17yrs old and I been having a hard time getting and keeping an erection, I have this problem during sex and masturbation. I don't know what to do, I have tried masturbating less, but the problem continues. I have heard of this with older men, but I feel I'm too young to have this problem. I heard this could be an anxiety, but I dont seem nervous or anything. Does anyone know any remedy, foods, or vitamin/pills (over the counter, I'm too embarrassed to go to a doctor about this).Also I've noticed I am a premature ejaculator...so does anyone have tips that could help, I'd appreciate it.

try masturbating before sex to prevent premature ejaculation.

getting an erection is all in your head. both of them. you have to feel relaxed. are you worried about pregnancy? that in the back of your mind might be causing it. try more than one form of birth control to ease your mind!
