Why do men need sex all the time?

In my discussions with women, I don’t think many women really know why this is. Men only seem to have one thing on their mind and why is that? What is it with this obsession? I think the true answer is very simple. The need for a man to have sex is fairly similar for the need to go to the bathroom, eat, or breath. What these have in common is that if you don’t do them for a while, a “pressure” builds up inside of you to compels you do do each of the acts required for survival. So, if a man goes without sex for a while, that internal pressure grows and grows with each passing day and he literally has to “gotta go!!”, “gotta go!!”. Imagine if you couldn’t urinate for a day. The pressure would grow to the point that if you saw a toilet, you would run to it. That would be the “only” thing on your mind. For many men, it only takes 2–3 days without sex to build up such urgency. But once a man has sex, that urgency drops off and he is likely to just nod off after he has been “relived”. This may have something to do with nature’s way of keeping a man’s supply “fresh” and women may not have similar urges. It isn’t like doing something that you “like” such as eating chocolate ice cream. You’re not going to die if you don’t eat chocolate ice cream. It is just something you like to do when convenient. But for men, it will absolutely drive them insane to not have a climax after a long while. It is much more like “starvation”, than doing…
