The issue is present clear through the animal kingdom with gays in near all species. At times it can have economic ramifications.
Years ago a coworker did some research with sheep. Seems there's about 5% rate of homosexuality, which is not a big deal if one has a flock of a 1000. If one is running 30 head of ewes and ends up with a gay ram, however, the lamb crop will be a little sparse come spring and not much of a market check come fall.
Anyway, the gay boys were indentified (n = about 20), presented with estrus ewes and all spent the days in the meadow grazing and smelling flowers. The next phase was to hop the boys up on hormones, going as far as using brain pumps and continuous injections with some directly into the brain. Those injections were enough to have even ewes up and riding a fire plug if it gave them a glance or smile.
In artificial insemination programs we'll often hop up a cow and she will go on the prowl and point out the estrus cows that are ready to breed. The upside is no danger of an unwanted blood line had we used a bull for the same task. The hopped up cow will still cycle and can be bred successfully, so we don't miss a calf from the practice.
Back to the sheep...
For this round of the project they shipped in some really cute ewes from Nevada, got some synchronized heat going, and still not a convert to be had.
Bottom line, it's not a hormone deficiency. It's an unknown physiologic or wiring issue and perhaps some day genetic analyses will discern the causitive factor/s. No evidence of it being a conscious choice deal.
My thoughts: To each his own and lets all be discrete with none of this in your face stuff.
