### input:
I m 19 years old. I have been masturbating since like 4 years, it started slow, but over time i started to masturbate way more often and i get to the point where i was masturbating like everyday, also i started to do this pretty rough, hard grip, without any moist. And i found out that masturbating this way and so often may be bad for my health, it seems like my penis isn t so sensitive as before, and i erect pretty fast. If i will stop, for long period of time, let s say month or two, will it back to normal, to old good shape? I m just scared that if i will meet the right woman, i won t feel sensation when i get inside her soft vagina, or i will climax, way too fast. What should i do? I already stopped masturbating.

Degree understand your concerns went through your details. Please understand, masturbation is not at all unhealthy. At your age, it is OK for you to masturbate once in a day. Masturbation is healthy, natural and stress buster. It is a natural way to throw out the waste product called semen. don't worry in that aspect. You should not hurt your penis by being so harsh on it. Reduce the pressure you exert and use some lubricants or pillows etc. while you masturbate. You can continue masturbation around three or four times a week without putting extra pressure or effort. You will be alright.
