In the eukaryotic fossil record, sexual reproduction first appeared about 2.0 billion years ago in the Proterozoic Eon, although a later date, 1.2 billion years ago, has also been presented.
Sex has been around for a while and such an elimination hasn’t happened, so my guess is that, unless changes in the environment make it a more-prominent negative selection factor, homosexuality isn’t going to be eliminated via selection of genes in the near future.
