hi, i am 17 and i was having sex with my girlfriend and she was trying to beat me off before sex. well she had gripped the very bottom and was pulling hard.and after she finished that we had sex. and about an hour later i noticed the base of my penis was the size of a baseball!now,for about 3 weeks,i have trouble urinating and my left testical line is swollen and doesnt seem to go down. i tried ejaculating and it just gets bigger.i am scared and the doctors dont seem to find out whats wrong,but i am still in pain and would like to know if anybody else could give me some answers.i am desperate and would like to know soon :(thanks.
