We don't need to understand every physiological detail of sexual attraction to find a "gay gene." Most genes that have been associated with behaviors are found by correlation (and those correlations are not 100%). The detailed mechanisms involved are usually not known.
It is also likely that someone's probability of developing a homosexual preference could be strongly influenced by simple things. There have been experiments showing how varying the intrauterine concentrations of particular hormones will masculinize or feminize rats (and probably other animals). Of course the same experiments can't be done in humans for ethical reasons, but I'm sure the principles are similar. It isn't very hard to conceive of a group of genes which would change the concentration of a particular hormone at a certain portion of the fetus' development. It could also modify concentrations of receptors for that hormone. Both of these possibilities are reasonable things to search for.
