Not just the size, also the shape, and also butts and thighs. Beyond that, torsos also tend to have idealized shapes, limbs are too long, and joints have also gotten unrealistically dainty. It started with the weird noodle people of the 90s, and while you can find a handful of partial exceptions like picrel, the full package is nonexistent now.

The problem is that requires intention. Artists stop improving once they meet their own standards, and it's what is passively absorbed that sets those standards. I'm seriously baffled by the amount of hentai artists who outright don't know how to draw a pussy. They've always been a problem, but it's so much easier to learn now that you'd think they'd at least try.
