About 3 000 years ago the Chinese traditional doctors came to the conclusion ( and developed a theory) according to witch , it is not only women who are limited in the number of fucks they get to have in their lifetimes but men too. While the women are limited by the number of eggs they carry, men, ( according to this theory) have something like 3 500 “releases of semen” ( I might not be remembering the number exactly) for their entire lifetime. And this includes masturbating. So, once we start reaching the final number, the quality of the semen drops, as well as the quality of the fucks given… Then, once the last load has been shot… that is it…

Funny thing.. how everything we think we are learning just now, has been known and sometimes even forgotten somewhere else….

BTW ( just saying) If I, or any other male writer wrote what you did about how “fucks” , and their importance, change with age … we would have been accused of sexism, slut-shaming, stereotyping women etc etc etc
