I'm sorry for being blunt here, but whoever is claiming that sex in BG3 is too gracious or is the main selling point either don't know what they are talking about or just writes it with ill intent. I have seen full Shadowheart romance, one Karlach's sex scene, two scenes with Lae'zel, initial sex scene with Minthara and additional sex scenes with Mizora, the devil in House of Hope plus drow twins in BG3 inn. None of those scenes were on any way more horny then we have seen over a decade ago in Dragon Age Origins and we really have no more than 2-3 sex scenes per companion, spanned across the entire game. If anything, I'm a little disappointed, Larian played safe after advertising it as more hardcore as it really is. So yeah, sex is a very minor part of BG3 and definitely not its selling point. And I'm talking from experience, take it or leave it.
