Anyone give any advice please!! Today I go to my friend's house, I played his PSP and he was watching porn. After that, he go to the toilet to masturbate I think.. Suddenly he shouted, "HOLY MOTHER F***!" I rush into the toilet and ask him what happened. He says that there's a blade-like scar on the skin of his penis and got some blood on it. Is it because the skin of his penis is dry and he rubbed it to masturbate and the heat of the friction made the skin worn-out a little like a small scar? He also asked me this question which I don't know how to answer... "Is it okay to masturbate 3 times a day?" So how? Someone give me any advice so I know what to answer him... There's also a news about a Japanese masturbate 5 times a day and over 10 hours in once and then died because it loss too much sperm and the heart and lungs stopped working because of it... I don't want he die before he return the $79 to me I lend him... Sorry for bad English, correct me if I used any bad one.
