hiii , i m 24 and i m boy, i do masturbation about two or three times in week. i know it is not harmful , but when i do masturbation it take very short time always, about one minute. i have not done sex till now , is it take longer time in real sex or i have a disease? also i feel have pee every night when i lie down even if i do it one minute ago. i had crystal in my urine about 3 years ago and i feel i have it now , but i think it is not all of the problem , because even if i drink a lot of water and pee with light color , i feel have pee. may be it is Obsession. but i m not sure. thanks
