Another interesting point for Perv is that individual men tend to have much narrower sexualities than individual women. This fits with my personal observations: women are more like to be bisexual, more like to switch in a BDSM sense, less likely to have a true paraphilia (something they cannot become aroused or orgasm without. As opposed to a kink, which is a non-standard sexual interest that someone enjoys but does not require for every sexual encounter). Of course, it's impossible to determine the extent of cultural influence from observation alone, but Perv introduces some animal evidence that males fixate to a narrower range of targets.

You might think that supports the idea that it's genetic, but it doesn't. The experiment in question swapped baby goats and sheep with each other, and observed the sexual behavior of the adoptees. Males of both species pursued females of their adoptive species, females remained receptive to both (book didn't mention the behavior of females adopted by the same biological species and I can't find the cite). Male goats do not have a sheep-fucking gene. What this actually shows is not that courtship targets are inborn, but learned from the environment, and that males narrow down their target in the time between birth and puberty in a way females do not.

This offers a really satisfying explanation for the range of human male sexual behavior. Most obviously, the wide range in beauty standards between cultures but narrow range within cultures, and in what an individual man finds attractive. Young male brains have the capacity to learn from the culture what is most advantageous to impregnate, and work with that, but have a hard time shifting targets later in life. It works for non-reproductive sex too: Pederasty will never result in a pregnancy, but if sex with young boys is correlated with gaining resources that will aid in reproduction (e.g. status in Ancient Greece), and the relevant section of the brain is taught that while young, it will find the idea exciting.

So once again, the answer to the question "what are humans programmed to do?" is "be astoundingly adaptive to local conditions."
