ok im 14 i mastubate 3 times a day and i love it but every now and then like some skin will rub off i know its gross but is this normal i wonder?
woah, settle down on the fella!!
seriously, after years of viggorous and creative masterbation, I've never rubbed any skin off.
Although, it sounds as though you might be circumsised, resulting in more direct friction. Try using some lotion when you spank.

If you beat the hell out of your penis, you will abrade the skin. Try using lubrication (cooking oil, saliva, K-Y, Platinum Wet, etc.).

could it be that he's just rubbing off some smegma (sp?) you know that white crap that you find under the foreskin if you havent washed.
