I'm not gonna go on race(I'm black and hispanic)because i've seen black,spanish,white,chinese,shit even indian hooded out guys.Do u think these types(lol i'm talking like I'm not one)are a little more endowed then the average guy because of constant stretching.Anyone familiar with this lifestyle will know that all the way back in the early 80's that u would see guys drinking a forty and grabbing-stretching their dick.I myself never made it a habit back in the day cause i was raised by nothing but females and they always commented on men that did that looked like they had some kind of std,ya know with the constant tuggin at their dick and stuff.How long has Pe been popular in the states,this site is so great these exercises are something i will share wit my son when he's in his late teens
