I think that this question can only be answered statistically. Because the masturbation behavior is dependent on age.
I am 72 years old and masturbate since my 9th year regularly d. H. Every day. (For many years I’ve masturbated regularly 3 times a day.) That’s 64 years. During this time I masturbated about 27 532 times. Even now I masturbate on average 1.4 times a week. Therefore, I have the exact numbers because I have out of interest a sex diary.
I tried to get along (masturbating) without masturbation at the age of 23, 21 days I endured, it was hell.
It seems to me that old long-time masturbators have the same problem.
My problem is that unfortunately I can not masturbate every day as I am used to it. The reason is that the erection fails and also the stimulation to orgasm is not sufficient because the penis has become relatively insensitive.
