GOOD MEN PROJECT: Consider what happens when you drop a male rat into a cage with a receptive female rat. First, there’s a sexual frenzy. Half a dozen copulations later, the fireworks fizzle. Even if she wants more, he’s not interested. His brain chemistry whispers, “Roll over and snore.” However, if a new female shows up, his exhaustion will miraculously fade long enough for him to gallantly attempt his fertilization duties. You can repeat this process with fresh females until the male nearly dies of exhaustion.
His renewable virility is not indicative of an insatiable libido. Nor does it increase his wellbeing—although it may look (and temporarily feel to him) that way. He goes after each new female because of surges of dopamine in his brain. They command him to leave no willing female unfertilized.
Scientists know this biological program as the Coolidge Effect.
Dopamine, the “gotta get it!” neurochemical behind all motivation, is central. Without it we wouldn’t bother to court, pursue climax, or even eat. When dopamine drops, so does motivation.
The more the rat copulates with the same female, the less dopamine he gets for his efforts—until he heads for the recliner, toting the remote.
Consider this graph. The fifth time a rat copulates with the same female, it takes him 17 minutes to get off. But if he keeps switching to novel females, he can do his duty in less than two minutes, five times in a row.

My boyfriend would rather masturbate to porn everyday than to have sex with me. He says its because it hurts his back and he is to tired.
