I remember the last PFH, wherein was stated that the 'romances were more mature' and 'it's not about finishing a quest and be rewarded with sex'
Well. It is literally 'finish Act 1 and be rewarded with sex with whomsoever you choose, they're all game'. Even the Mass Effect series wasn't *that* bad. Then there's the Emperor who, out of nowhere wants to bang you *regardless of your interaction up to that point* and gets angry if you don't want to. There's even an achievement tied to it, so if you want to 100% the game, you're locked into going that route, even though it has no impact on the game whatsoever. Then there is Halsin and all his 'I am the legendary sexmaster' stuff in Act 3. Granted, BG2 had moments like Minsc shoving Boo where the sun don't shine, but still. Haarlep *can* be avoided, but come on, man. The interaction you can have with Haarlep is more than you will ever have with actually important characters, say a certain servant of Bane. Not only that, but take that route and you're rewarded with even *more* narrated sex afterwards. Humorous to some, perhaps, erotic to others, but I find it cringeworthy at best. Maybe if I were fifteen, it'd summon my Netherese Wand, but as an adult I just roll my eyes at it. If they refrained from all that nonsense and instead paid some attention to actually important characters like Gortash or the Emperor, the game would be far better for it.
Astarion's vampire reveal scene is also unavoidable, and rather sexual in nature, that's backed by the fact that - choosing to go along with it starts his romance [not to mention I've seen a compilation of girls who collectively cast create water at this moment]. Now, you can kill him for it, too - and I always do - but I can't *avoid* it, either.
On top of that is the 'game doesn't recognise gender' thing. I get it, modern audiences and all that... But there's no way to opt out of it, and I'm forced to deal with getting chased by everyone, including those I'm not interested in. And there's hardly any saying 'no', or go; 'Hey man, I'm not gay/straight' to get the message across. If you let me choose my gender and pronouns and all that, give me a 'I'm straight/gay button' so I don't have to deal with things I find disturbing.
And lastly - and this more or less equates to my previous complaint - The game assumes you pick at least one character to romance. So as long as you don't pick someone, you're game for the rest of them. This is annoying as hell. Even Withers complains to you for not banging at least one of your comrades. For me the problem, mostly is then - That I don't chase NPC's, yet they chase me.
