So far as I understand, there's a belief (not entirely unsupported, although I don't know the details) that sexual orientation is a relatively immutable property of the individual, built in from a young age if not from birth. I think "innate" is a fair description of that. But I don't know that there's any particular beliefs about whether that property (sexual orientation) as encoded directly in the brain[1] is "prefers men" or "homosexual", which I think is what we're discussing here. This is why I suggested "epistemic primacy" - whether other things we can say follow from "homosexual" or whether it follows from other things. [1] for those who even subscribe to a physical understanding of consciousness - we're talking about a diverse group; otherwise we can possibly find an equivalent notion
