I would be incredibly uncomfortable if someone were to draw my model being fucked. It would feel like I myself was being violated. I dont want it with a male or female. But im super okay with bikini and lingerie. I wear that now so it would be no different. But that doesnt mean I wanna sleep with a random stranger.
Someone can be lewd and like lewd things but doesn't mean they want to be drawn getting fucked... A lot of us Vtubers put ourselves into our models so makes sense if someone doesn't want NSFW art of their model but be okay with sexy bikinis.
Respect boundaries. It isn't hard.
