I'm fifteen years old.

I've tried all sorts of masturbation techniques from the Internet, but I just can't cum while awake!

I can have erections, but there's little to no sensation at all. When I try rubbing the tip of my penis, I get this sensation that feels kind of like pain--not that it's *painful*, but it's still somewhat unpleasant, and I have to force myself to go further. But nothing I do can even cause precum.

I only began having waking erections recently, after I (almost) got a girlfriend for the first time, which I guess relieved some sort of anxiety issue. Before that, I had the same problem with erections.

At some point or another, it'll be my obligation to cum, so I need to make sure I can do it healthily, for long enough and that it's an acceptable hue. I'd never masturbate for pleasure alone, but that obligation forces me to seek help from you guys.

I can't really speak to my psychologist about this, since they'll probably prescribe something, explaining it to my parents. It would be a waking nightmare for my parents even to know I have erections, let alone talk about my sexual health.

I got facial/pubic hair pretty early, so I don't think late development is an issue.

Thanks so much for any help! =D
