Female rats are not passive sex partners: they pace the encounters and will run across an electrified grid to gain access to a male.
Sex fortifies the brain (in rats, at least), stimulating the growth of new neurons and neuronal connections.
Rodent females are choosy, traveling up to seven city blocks—a long way for a rat—to find a male who meets her standards. She sniffs out his biological germ-fighting arsenal.

In the reality television shows The Bachelor and The Bachelorette, 25 potential mates vie for a desirable male or female during a series of artificial encounters and interactions. The most attractive candidates are given a rose each week, a gesture indicating their special standing among the others. These shows are saturated with cultural icons representing romance and desire: physically beautiful people, bikinis, hot tubs, gourmet meals, adventure dates, champagne.
