better wanking than smoking!
I'm not disagreeing, but is there actual evidence that it is beneficial to the health?
I have to disagree. In my country we have many religious people that I'm sure major part of them (at least 60% IMO, probably more) never jerks off due to extreme education and strong belief it's evil action. And still, they all have LOTS of children and rarely have fertility problems. So even without replacing it every day, the sperm is still active.There's an argument now that it has evolved into us because wanking helps make sure fresh, mobile sperm are available to you instead of sperm that has been sitting around for a while that isn't as mobile. So, basically, we're bound by evolution to want to wank as often as possible!
