I think sometimes people see romance in a fantasy game as they would in RL, sitting at their homes and going out to meet a nice gal/guy. one possibility to think about (not saying its necessarily true) is that Larian, unlike other RPG games, got "romance" right. If we do not confuse "romance" with "love story/deep relationship" this is one way to look at it. Anyone whos been in RL in summer camp, probably knows how fast people who don't know each other previously can get to banging, in a matter of one, two three days. Now imagine a group of people, in a risk for their lives, not knowing if they survive the next day, living in the same camp day in and day out, a lot of them with issues, they have a party, they are scared/worried/ angry and kind of lonely, drunk, why not look for company, sharing a drink and sex? people in much less depressing and desperate situations do that in RL and a lot. Its not "Love story/ deep relationship of the ages" maybe its not even the classic "romance" but it happens, and it can be fine, not rushed or weird.
Now, I would have a bit of issue if these are the only companions in the game and *all of them behave the same way, are open sexualy and would look for sex to distract themselves or finish a party, just like in RL some people and companions should be different or more reserved or have other tastes and less of "fuck all" and "do what ever the fuck I want" mentality. But right now, for mostly evil and selfish type of companions (I personally didn't get this kind of reaction from Gale, but maybe his approval wasnt high enough) It can be seen as rather realistic and refreshing take on "romance" in games.
p.s
It is also a matter of taste and the companion personality, I remember in BG 2, I used to get so bored with Aerie's "deep and true love" and slow burn romance. While in Viconia's case, sometimes you would have sex very quickly (if you don't reject her) but it would lead to an amazing very complex, true and fascinating romance and journey
True. I romanced Shadowheart in my playthrough and in the day after she said it was a drunken mistake
