Lately ive been enjoying squeezing my testicles, just started doing it and find it a turn on. Had my nuts suck plenty otimes but this squeeze thing has got me going.
Yeah, as long as they aren't squeezed so hard that it's painful.
There is a cremaster muscle which surround each testicle. As a male becomes sexually excited, the cremaster and a couple of other muscles pull the testicles up, until at ejaculation, they pull the testicles tight against the body. I'm no doctor, but I think that squeezing your scrotum causes the testicles to retract--and we all know that feels good--especially when it leads to ejaculation.
