> Sex is similar. We are descended from males who mated with as many women as they could. Maybe not all men are like me, but there is a part of my brain that literally wants to mate with every attractive woman I see.

Not quite. We are descended from sexual pairs whose children survived long enough to reproduce. Often, it took at least both mother and father to keep children alive. And human female reproduction selects for males who stick around, primarily by hiding most signs of ovulation, unlike many other mammals with obvious signs of momentary fertility.

But you're not wrong either. Both male and female reproductive strategies want to maximize number and viability of offspring, but the female cost is much higher than the male cost in time and energy, so males can theoretically roam more easily. In the past, mobility and low populations generally limited that ability (though Genghis Khan managed). That's the disconnect between prehistoric and modern humans that porn and dating apps exploit.

Often the "father" who helped care for the children was not the biological father.

"It takes a village." Extended family care and smaller tight-nit communities were more common than they are now. If you're talking about extra-pair paternity, it's estimated to be only 2% in humans.
