I think so. I've never actually hurt myself like some of these other guys. close, but worst for me was blisters. but you do have to be careful with cutting off circulation, that's why you never sleep with an extender on and never go to hard with it. taking off an extender to see a blackened penis is terrifying and not something I want to see more than once.

I've gained about .75 inches so far, which is better than nothing. probably would be more if I dropped a few pounds too. honestly that's probably your best bet first, dropping extra weight to get to 12% body fat, then from there you could see if you want to risk it.

start light- stretches, light extender

then maybe pumping and hanging

but you gotta accept yourself where your at or you'll end up like some of these guys with warped minds thinking noone will love them if they aren't 10+inches (a slight exaggeration but the underlying point is true)
