Due to Multiple Sclerosis, I have reduced sensitivity in my penis and have a tough time achieveing orgasm through oral sex or intercourse. I can through masturbation, but have to apply more pressure than most probably do, and often have to really concentrate on it. Does anyone know of anything that increases sensitivity so you can ejaculate more quickly/easily?
Men who restore their foreskins by stretching report increased sensitivity but that's a long term commitment and you would have to want to have it back too. That's if you are circumcised too. I don't know of anything else.
I once tried a supplement called Yohimbe. It is used sometimes even by doctors for ED. It did seem to increase sensitivity somewhat for me but it also has side effects for some (including me) like making you feel hyper and making it hard to sleep. So I don't know that I can recommend it but you could try it once.
