CBT, in our opinion, gets a bad rap. Okay, it stands for Cock and Ball Torture, which means it's a hard sell for a lot of men! But really, when the squeaming stops, it's not half as bad as it sounds (at least not the way we do it).
Mostly what we're talking about here are constrictive toys, little helpers that simultaneously heighten sensitivity and delay ejaculation. What's so bad about that? Some of the toys (I'm looking at you, Pleasure Gates) are tight, no doubt about it. And you could say they hurt, but it's a good kind of hurt. You have to remember that in the moment your body processes pain differently, and releases chemicals in the brain that bathe you in bliss.
If you know about CBT, you know this already. If not, it may be a leap of faith. But a leap well worth taking!
