I am 14 y.o. and I masturbate a lot(sometime everyday). At least twice a month I'll have pain on my shaft after I finish about an hour later. This usually happens when I get an erection after I finish. I'm worried it could be a big problem. I am a virgin also. I read it could be a prostate problem and I am worried it is. Coudl this be caused by vigorous masturbation making it sore? I do do it hard sometimes. Please help
Do it much softer. A good way to masturbate is take a wet Qtip and whisp it down the shaft. Handjobs should not be done too vigorously. And if you find masturbating painful later, you should be treated by a doctor.
