I'm not interested in Larian's awkward sex scenes, but it's a fair criticism of early access that their romance isn't very... romantic in style.
I'm not sure about that. I'll admit that though I enjoy there being romance options in games I tend to find watching them play out a bit cringeworthy in practice, but I wouldn't say that at least some of the EA scenes aren't romantic at least in intent. There's stargazing with Gale (once you get past the sex book talk), the Wyll scene can end up quite romantic especially if you decide not to push it with Mizora (I don't much like the scene, but not because it's not romantic), and I think the Shadowheart scene is lovely. Astarion's admittedly isn't romantic, but then that's kind of what you expect, and I've only tried Minthara's scene once and Lae'zel's not at all, but while I don't expect they could be described as romantic I think three out of six isn't all that bad.
(And then I'd say the Karlach scene we saw in PFH was definitely romantic, but that's not relevant if we're talking about EA.)
4 romances fir each gender is fine. The issue is there's not enough variety. There is no hetero or gay romance. It's all bi. Lol Thete is no dwarf romance, no orc romance, but there is a bear romance... so that's kewl fir those into animals. Lol
Personally, I don't see playersexual characters as necessarily bi. They could be, of course, but they could also be straight in some playthroughs and gay in others. We're free to interpret them however we wish, based on the information we get in game. We don't know exactly what info we're going to get about the BG3 characters yet, but to take a different game as an example, in DA2 I'd always see Isabella as bi, whereas Anders I'd tend to think of straight if my female Hawke was romancing him and gay if my male Hawke is (though of course it would be totally valid to interpret him as bi too). For me, just as my own player characters can be different in different possible worlds, so can NPCs.
And, while I know it's a joke, I feel that when we're actually debating the topic of variety in romance, we should be more precise in our terms

Halsin is an elf, and a person no matter what form he's in, so there is no need to be "into animals" to enjoy romancing him.
