You're conflating two groups and in an odd way to boot; the people who remark that BG3 is far more zany/over-the-top with its particular brand of humor compared to its predecessors are among the first to point out the first two games did feature nudity/sex/sexuality.
I don't conflate them, I am merely pointing out that it's yet another misconception that exists, potentially because the people played those games long ago or have arbitrarily forgotten about certain things.
P.S. The presence of nudity/sex/sexuality does not automatically/inherently indicate perversion, despite what some people think.
I meant it in a light-hearted way. BG1 in particular was a carousel of random nonsense, including an occassional below-the-belt moment/joke just for the heck of it (Imoen's "trollops and plug-tails" quote immediately comes to mind). Whereas 2 would go down the aforementioned "edgy" direction with the stuff, making it unsurprising that the same writers/authors would later be responsible for the Dragon Age games. They are anything but down-to-earth and matter-of-factly with the subject matter in question (the "This is the new sh*t" trailer back in the day was... a choice). If anything, the tone in BG3 is quite similar to the one from the older DA games, before they turned the setting into a hipster coffee parlor.
