A few years ago, I speculated on how
some variety of male homosexuality may have evolved through the symbiotic interplay of kin-selective
"female surrogacy" and socially facilitated cuckoldry. Of course I assumed that
my armchair hypothesis was probably wrong, but every now and then
I come across anecdotal points that make me wonder. First, there was the cross-dressing cuttlefish. And more recently, the quant blogger cum Roissyphile known as "Agnostic" posted some thoughts on "why straight men rationally dislike gay men" that prompted the following comment:
Another reason to beware of your wife's gay boyfriend: In the ritzy
suburb of Palo Alto, California there was a few years ago a guy who
murdered his wife who had long ago cuckolded her. The couple were real
estate salespeople during the real estate boom, and the murder came
about long before the bust. The murder came about because the
cuckolding became public when the wife revealed to their son who his
real father was, after she had promised to never tell. This shamed the
husband and brought back bad memories, and he just couldn't stand it
any more.
The cuckolding occurred because his wife insisted on
inviting her gay boyfriend camping with them. Sweetheart, if you want
to be my husband, prove to me you're not a homophobe by bringing my
friend along. The husband obliged in this harmless proof of his
political correctness and ended up spending all the rest of his life
(a) raising another man's child and then (b) in prison for taking
revenge for (a).
Most gay men are bisexuals who normally find it
easier to score with other gay men than with women. Lesson learned the
hard way.
While I don't agree that preferential homosexuality is typically a strategy of convenience, there's no question that the scenario identified by the commenter ... happens. I've seen it come up on daytime talkfests, and I've personally known "fag hags" whose close friendships with gay confidants have intermittently lapsed into sexual misadventure. The question is: how common are such occasions? Are they more common in polygamous social environments where effeminate males might enjoy greater access to the harem over the long haul? Are they common enough to open the side door for the penetrance or sustenance of elusive gay genes?
My understanding is that the data on cuckoldry is all over the map and I assume that most furtive fathers are cads rather than lads, but if anyone knows of relevant research, I'd be interested.
Memento mori.
