For best outputs and usage:

Sampler: DPM++ 2S a Karras

Steps: 36, cfg 4.5 ~ 6.5, CLIP skip 2.

VAE: sdxl_vae.safetensors

Pos prompt: start it with "score_9, score_8_up, score_7_up, score_6_up, source anime, rating_explicit". The model isn't anime exactly but cartoon, but source anime gives it some more of quality. Also, "rating_explicit" is mandatory if you want sex scenes in most cases.

Neg prompt: begin it with "score_6, score_5, score_4," plus what you don't want to see. For example, for most of my example runs i used "score_6, score_5, score_4, disembodied penis, double glans, missing boy, oversaturated, busty, ugly face, mutated hands, low res, blurry face, pumped body, athletic body, sticks, muscular female, bad anatomy, bad proportions, deformed, deformed anatomy, deformed fingers, cartoon, skinny, long torso, messy_hair, censored, lips, long neck".

The model doesn't listen as well as other pony models but still listens really well, and very probably it will be able to create what you need. Feel free to check my example runs.
