Slightly off topic possibly.
I have been jelqing, kegeling etc and they definitely help to give a harder erection etc.
I still have a problem where I cum too soon, literally after just 2-3 minutes normally. The only way to prolong this is to take a break before going back. It also doesn’t just apply to sex but masturbation.
I think I must have an unusually high concentration of nerve receptors in the head of my penis. Although this makes more pleasure the downside is less time spent.
Any recommendations on this board beyond the exercises I am already doing?
