crazy2009:I have had something similar and it's a pain in more than a few ways it maybe the foreplay that is the problem in that the oral she gives you have u ever thought she has scrapped u with her teeth and flinched. The other is do you shave remove scrotum hair from yourself and if so perhaps as has happened to me u have literally stabbed yourself on minute hairs that start to grow back just a couple of things i have found over the years may not be the answer but offering up
yeh, its def not foreplay but it could be the hair thing. i will take notice next time it happens
