I am 72 years old and masturbate since my 9th year regularly d. H. Every day. That's 63 years. During this time I masturbated about 27 458 times. Even now I masturbate on average 1.4 times a week. I can not say that it's still a lot of fun. It's still fun. Since I am 55 years old, I notice that the sensitivity of the glans (glans) decreases. Each organ responds to stress.
Examples:
Hands are chafing through heavy work.
The soles of the feet become thicker and less sensitive due to Bahrfußlaufen.
The glans (glans) becomes less sensitive by pruning because the skin gets thicker.
Etc.
When masturbating at a mean masturbation frequency of about 12 Hz and a medium masturbation time of 2 min, 27 532 times, the foreskin has been opened about 39646080 times. I think the Glans reacts too.
I still remember how sensitive the glans was at the beginning of masturbation at around 9 years old. The thrill was almost unbearable so that I had to interrupt the masturbation.
This has normalized over time so that I could always masturbate with pleasure.
It was not until the age of 50 that sensibility declined noticeably.
But even now, at 72, I still manage to masturbate with pleasure.
I start with the 3 finger method, i. Middle and index finger on the bottom of the penis and thumbs up. If then the excitement potential increases I take as before the whole hand.
As a lubricant, butter has been found to be best over time.
I suspect that this reduces the frequency of masturbation per week from a maximum of 19.6 times / week to 1.4 times / week. From about 45 years, the masturbation frequency begins to decline. Therefore, I have the exact numbers because I have out of interest a sex diary. So I'm already of the opinion that masturbation is an important and beautiful sexual activity.
