I do think that there's an innate component to attraction, just as you suggest.

But we also know that mental habits, repeated for years, become deep visceral reactions. And society programs our unconscious attitudes in a way that's difficult to appreciate simply through conscious introspection.

It's actually hard to know what you'd be attracted to, if you lived in a society that truly accepted/encouraged same-sex attraction. Maybe you'd be the same. Maybe you'd have dated guys once or twice, but ended up straight. Maybe you'd have five kids with a male partner. It's hard to say - it's an experiment that hasn't been run.
