Masturbation - uncut vs cut?

I never realised it was such an issue for masturbation! I am uncut as I think most (well non-jewish) guys are in the UK. I often thought it would be good to be cut for the exact reason that my glans would be less sensitive so I could last longer during sex. But the other day I was so pumped with a cockring on that I had no play with my foreskin and tried to edge and ended up with a torn frenelum! Ouch I know. Now I want to keep my little bit of skin.

I am so glad I have my forskin. It makes jerking off and sex so much better.
