Does masturbation affect penile health?i can ejaculate but my sensation of touch on the penis was more when i was younger. can it be improved?

Masturbation: Nope. Masturbation in general is a normal common part of the human experience. In general masturbation is not dangerous to your health. There is no medical or scientific reasons to limit masturbation. Now sensitivity questions can have a lot of different answers and you may be wise to get to a men's health expert. But, my first thought is that you may need to add some lubricant to enhance.
