Gemini (or Nano-banana) censorship isn't as much strict as it is ridiculous, inconsistent and unpredictable. You never know what may cause it a prudish fit tomorrow. Lately, it have been female lingerie-clad butts (not naked, mind you, while naked butts are too technically not pornographic at all). Front view in the same undergament - no problem. Back view - oh, no, the horror! And yes, bikinis that cover significantly less skin work just fine.
Still, I enjoy what I manage to get out of it (sexy outfits, fetish fashion, panty peeks, lingerie, stockings, bikinis etc). Also it does entranced, pleasure-drunk and generally sexy faces pretty good.
To generate explicit stuff I found Qwen Image to be okay (by expicit I mean just the female full frontal nudity, not the actual porn stuff). The style, however, is not completely to my liking. Has a somewhat "plastic" feel to it.
Also, there's always an option of post-production in Stable Diffusion, but it's too much pain in the ass, usually.
