I don't really get this argument. Titillation occasionally is nice. Similar to prestige shows. But if it was soft-core all the time or too much, people would lose interest in the plot.
That and there's quite a few decent porn games now. Ones that look better in the...dongles than BG3 does. Ones with decent stories. If people want interactive porn, it's there already. And oftentimes cheap or free.
