I think your starting point is still kinda skewed, because "heteronormative" is a made-up thing by society rather than an actual thing someone can be.
There's a traditional view of sexuality that men are only sexually attracted to women, and vice versa, and that's normal and everything else is not normal (kinky). The more we learn about sex (and gender) the more we learn that there are very few completely "normal" people out there, and a lot of people who are a bit kinky in one respect or another. I think it's now accepted that the hetero-homo thing is a spectrum rather than a binary state, and the primary reason people of the same sex don't have sex with each other is societal pressure rather than biological attraction. e.g. women tend to experiment more with this because society has a more lenient view of "girl-on-girl" than male homosexual sex.
My personal opinion is that evolution "wants" everything to fuck everything as much as possible, just to see what happens. The best reproducers are the ones who did the most fucking, after all. But we're getting into Oglaf territory here.

It's a term rooted in the conditions that make sex a reproductive act and not just something that feels good
Which is getting back to the religious crap of "sex is only for reproduction, between a married couple". Yes sex can result in reproduction, but I think making that its primary purpose misses the point. We experience a desire to fuck, separate from our desire to reproduce. They're two different things that are only related in a tiny minority of circumstances. Classifying someone's sexuality by its possible reproductive outcome is like classifying their tongues by the ability to curl into a tube: kinda valid, but not that useful.
