Here's a wildcard of 75 different sex poses from Danbooru's tag listings at:

https://danbooru.donmai.us/wiki_pages/tag_group%3Asexual_positions
https://danbooru.donmai.us/wiki_pages/tag_group%3Asex_acts

Couldn't get all of them to be consistent, and some didn't really work at all without LORAs. The following LORAs are in the list:

https://civitai.com/models/881796/kneepit-sex-femdom-pony-and-illustrious?modelVersionId=1707973

https://civitai.com/models/543154/reverse-fellatio-lora-or-ponyxl-and-illustrious

https://civitai.com/models/1194983/navel-fuck

Nipples and navels might be too weird for /h/ but they're in the Danbooru lists and a nice 75 felt better than a weird 73.

They're largely pov/faceless male/offscreen male shots, though occasionally a duplicate character like pic related will be generated.

Mostly uses "looking pleasured" for expressions which is a less extreme look, but smug is in there for some of the more femdom poses and ahegao for some of the more rough poses.
