Here's my personal realism model that I've been using for a few months now. It's based on Pony Diffusion so just know that going in. It's really good for solo female and NSFW, of course.

My settings:

• Euler A (automatic)

• Steps: 20

• CFG Scale 4-6 (can go up to 10 but lower values generate better skin)

In the main prompt, I use:

• (score_7_up, score_6_up, score_9, score_8_up, score_8)

• Danbooru tags will 100% work
  

In the negative, I've always used:

• score_6, score_5, score_4, ugly face, mutated hands, bad eyes, bad teeth, bad arms, missing limbs, poorly drawn face, three feet, fused feet, fused thigh, three thigh, fused thigh, extra thigh, missing fingers, extra fingers, ugly fingers,amputation, square jawline, mutilated, deformed, disconnected limbs, abs, ribs, artist watermark, artist signature, watermark, signature
