hello im 21 years old, and i have a very embarrassing and worrisome problem thats bothering me. ill begin by sayin that i lost my virginity at 17 and while ive never been as sexually active as id like to be, i never had any problems with maintaining an erection or controlling myself in bed. but not too long ago, maybe a year or so, i would get this itch in my genital area and i wouldnt be able to help myself but to scratch it. well, it seems that one thing led to another and all of a sudden i seemed to have "scratched off" some skin from both my scrotum and penis. now it just looks like my genitals have slightly different skin tones and the skin is thinner and you wouldnt even really notice these nuances unless you were trying to so i dont really mind that and neither do the girls, though sometimes my scrotum and penis becomes very dry/wrinkly in these spots and if i rub gently or touch it then dead skin flakes might come off, and with the other unaffected areas of my genitals this isnt an issue. thats one thing, if you have any ideas about that or know what it is or how to treat that, i would be grateful. now onto my problem. it seems that now when i masterbate or have sex i cant last more than a few seconds after my penis gets friction! now, the last time i had sex i went after only a few seconds inside then i couldnt seem to get it up again, and i didnt have this problem before so im wondering if my penis is now much more sensitive since the skin is thinner or what? i havent been to a doctor or urologist or anything yet but im going to, in the meantime i wanted to post this to see if theres any other men out there with the same/similiar problem and if theres any way to treat this? im only 21 and this will greatly affect my sex life, therefore my social life, therefore my ENTIRE life and im desperate, im very concerned....
