Hi, i have 16 years, and i have never had an orgasm. i often masturbate, but every time i do that, i need to stop very quickly, because after few pleasent minutes, it starts to feel very unpleasent, so i can't stand it any more. I'm a bit of woried, i don't know if there is something wrong with me, but i do enjoy it every time i start to do it. what could be the explanation?
the part at the end that feels really good is the orgasm, after I orgasm its always unpleasant afterward
