>>29217680You know. I'm 100% sure that you're doing it wrong. Okay, that's just exxaggerating, but hear this. I can make myself to not cum with a slight movement. That's when I'm sitting and while I'm getting more horny, I flex my ass muscles really tight. The reason why I lose my erection and orgasm becomes impossible is in the nerves.
If you're wanking really hard for 40 minutes and you can't cum, then that's not death grip, that's your pelvic muscles getting too tight.
If you don't believe me, try this.
Take a regular chair where you can get up and get down quickly. Now, jerk off like you do. When you notice that you can't cum, or you feel the need to jerk harder, stand up and "twerk". Shake your booty and you can continue jerking off while doing so. Keep your hips loose and shake your ass.
You may even find your erection getting stronger and your sensitivity getting better.
Try that and see if I'm right or wrong. It's just that I happen to know I'm right, because you can't squeeze your cock to dead without squeezing your own hand dead too!
