Yes, it is more than 40 million years since humans have done this natural sexual behavior, but still, it is a shame to talk about it. I think the main reason is the religious beliefs ade treatment, which condemns it. One of the main religious ideals is to keep and prevent the development of human generations to increase population in the past, but, in the present situation which the world has climate and population crises this idealogy is gone. Masturbation could be one of the main parts of sexual activity that should talk and teach it in schools, it should be a part of essential education courses in school and it is also a great duty of parents to teach and treat their children about masturbation.
40,000,000 years of wanking... you aren't talking about the total time spent masturbating by the folks over here on our forum, by any chance? Here's to another 40 million years... and may the reign of masturbation last many, many times longer than that!
I love to masturbate. And if there's an afterlife, I would be happy to contribute my part to the next 40,000,000 years. (Unless of course Farrah Fawcett might become interested in me, in which case you're on your own!!)
