Jesse Bering complicates the Sex At Dawn discussion:
Heartbreak is every bit as much a psychological adaptation as is the compulsion to have sex with those other than our partners, and it throws a monster of a monkey wrench into the evolutionists’ otherwise practical polyamory. It’s indeed natural for peopleespecially mento seek sexual variety. My partner once likened this to having the same old meal over and over again, for years on end; eventually you’re going to get some serious cravings for a different dish. But I reminded him that people aren’t the equivalent of a plate of spaghetti. Unfortunately, we have feelings.
Bering, who is gay, explores jealousy in gay and lesbian relationships:
[S]exual jealousy in gay men can only be explained by some sort of pseudo-heterosexuality mindset simulating straight men’s hypervigilance to being cuckolded by their female partners. All this is to say that I reacted the way I did [to be cheated on] because, at an unconscious level, I didn’t want my testiculared partner getting impregnated by another man. I don’t consciously think of him as a woman, mind you; in fact, if I did, I assure you I wouldn’t be with him. But tell that to my gonads and amygdalae. I would imagine the same is largely true for lesbian relationships; at an unconscious level, a lesbian’s bonding with another woman may trigger concerns in her partner about her “male” spouse’s disinvestment in real or prospective offspring.
