What he said.
But you know, it’s your dick, you rub it with whatever you want.
Personally I think it’s retarded, but there are a lot things done here that people might think are retarded. Whatever floats your boat.
I will say it’s absurd to equate Scotch-Brite with jelqing or edging; they are all completely different activities with completely different effects. If your friend is cumming quicker after three months of jelqing, then he’s under a misapprehension that jelqing will make him last longer. Jelqing is supposed to make your dick longer, if he wants to last longer he really should try edging instead. As to jelqing making him cum quicker…I think he must be doing something wrong. My guess is he’s doing sex wrong.
If you want to last longer in the sack you’ll be much better served by learning your body, finding out how it works, and attempting to maximize your abilities. That sensitivity was put in place for a reason. Good sex is about learning how to ride that wave of sensitivity and make the most of it.
It’s not merely a mechanical practice, whereby you’re somehow expected to slide your cock in and out at some prescribed rate for an unlimited duration, regardless of how it feels. It don’t work that way. And it’s a damn good thing it doesn’t.
You also should take a cue from the vast majority of respondents on this thread; there are precious few that seem to think the desensitizing (especially permanently desensitizing) idea is a good one.
