Exactly. Larian put sex front and center during marketing and development.
- Marketing took off with the bear sex scene, displayed at a prominent event. - Nudity and genital customization was part of marketing despite not being really needed considering the outcome. - Sexual encounters were set quite early so even EA players got teased by them (see also the sex speedrun) - Established characters were rewritten because they were not likeable and romanceable enough in EA - Halsin was made into a companion purely because people started thirsting for him. But because of the time pressure the only content he got was sex as that was apparently the most important thing. - The vast majority of new content after release was about sex and romance.
Its quite obvious that Larian considers romance and sex one of the main draws of BG3 and marketed it that way to the detriment of rpg content as companions were filed down to visual novel level to make them "sexable". Thats in addition to Larians decision of not only make everyone Bi but to also have everyone romanceable, no matter the circumstances. Compare that to Owlcat rpgs, for example.
Just compare the marketing and content/companions to other rpgs. Not even Bioware focuses so much on sex as Larian does and they invented that trend. The closest ones were Witcher 1 and they reduced sex once they became successful instead of doubling down on it.
