For best outputs:

Sampler: DPM++ 2S a Karras.

Steps: 30, cfg 7, CLIP skip 2.

VAE: none required.

Pos prompt: start it with "cinematic still, cinematic, hyperdetailed, hyperrealistic, intricate details, vignette, highly detailed, high budget, bokeh, cinemascope, moody, epic, gorgeous, film grain, grainy, centered".

Neg prompt: "nsfw, nudity, ugly, deformed, noisy, blurry, low contrast, (watermark:1.2),, anime, cartoon, graphic, text, painting, crayon, graphite, abstract, glitch, deformed, mutated, ugly, disfigured".

Notes about the NSFW: Despite the model being capable to create complete nudity with male genitalia included, this model doesn't seem to have been trained into sex positions of any kind, being unable to produce such outputs natively. (The exception: it's capable to create blowjobs, but it won't go beyond this, that's why it's being released as a SFW model, including the keyword "nudity" in the neg).
