I've never believed that behaviours could be attributed to genes.Only tendencies. And you could have a positive selection pressure for tendencies as they would come in handy for other reasons.
So, yes, there could be a range of gay alleles (not exactly genes) that are preserved in a population despite the obvious problem of passing on a tendency not to breed.
