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.
As far as I can gauge, this is historically a trend. There's relationships and then there's *situationships*. Maybe SH and Halsin have potential for more. I could be disappointed in Karlach and Astarion. I don't trust Wyll and Gale at all to be genuinely interested. You're evidently just there and an option. Wyll, at least, is honest about that.
Wyll and Gale may be good to neutral alligned, but they're bottom of the barrel choices. The only redemption for Larian here is Halsin. There's one good female option and one good male option, so as far as I'm concerned, everyone gets equal quality. In the B tier, we also have Karlach and Astarion. One male, one female. I'm putting Karlach in B tier only because of the voice acting, though. Astarion, because although he's an amusing squirrel, there's not that many simps.
I'm not genuinely interested in any of them. If you don't like SH or Halsin, you're... kind of screwed in Bg3. Luckily enough for Larian, they're both likely to be popular if nothing else.
(I still hope there's some non party members to pick up the slack left behind by 5 more or less unromanceable or D tier picks. If not and Larian at least does 4 romances well, that's... possibly better than average for them? 4 isn't vast, but it's not bad, either.)
