Replace all the references to sex with food/hunger in your statements - "What is the big deal about food anyway? Why do some guys go crazy if they can't eat? A lot of time and effort for what, ten minutes of deliciousness?" I think perhaps it will make sense?

The reason libido is referred to as a 'biological drive' (definition: "an innate motivational state produced by depletion or deprivation of a needed substance (e.g., water, oxygen) in order to impel behavior that will restore physiological equilibrium.) is that it's a biological "need". Quotes because while you obviously don't need it to survive, the brain feels the same way for some people that it does when you "need" food.

it s not a need though, nobody died from celibacy. there are thousands of men who choose to become monks etc forgoing sexual pleasure. it is a drive, but not a need

I'll just repost the relevant part of my comment:
