I am 65 years old and masturbate since I was 9 Age on a regular basis ie daily. (For many years I have masturbated regularly three times daily.) That's 57 years. In that time I have masturbated about 26 900 times. Even now I masturbate on average 1.9 times per week. I have therefore the exact numbers because I have had interest from a sexual diary. Check out the link at times, I'm Mr. Z.

I've tried (out of interest) get along without masturbation at the age of 23 years, 21 days I have endured, it was hell.
Addict on sexual behavior, there is still an interesting link.

It seems to me many years old masturbators have the same problem.
My problem is that I no longer masturbate every day like I'm used to it. The reason is that the erection fails and the stimulation to orgasm is not enough because the penis has become relatively insensitive. Sperm production runs but still on high level, leading to tension and fullness in the prostate area. So I have to masturbate 2 or 3 times per week, because I have apparently lost the ability to pollution over the years. By the way, if I can trigger an orgasm so that is very pleasant relaxing. The orgasm takes place in several waves 5-7 highlights that was not formerly Sun
At the AGM I'm long gone to the climax. That is probably my insensitivity to the penis, caused by the many masturbation over the years although I am not circumcised.
question:
Is there evidence that goes through many years of masturbation, the ability to get a pollution lost? And therefore builds up the tension and the feeling of fullness in the prostate area.
