Not sure exactly what to call this but it adds some helper terms to style pelvic curtains/loincloths.
Supports:
pelvic curtain aside
erection under pelvic curtain
penis peek
Prompting for penis with the last two options seems to break it but you might be able to get some control over the member size by prompting the option tags.
Triggerword: pelvic curtain
FYI This dataset contains zero men so if it works for men, great but I have not and will not test for it.
Side note: I do take informal requests(basically a bounty that you don't have to pony up buzz for) if I like the idea(Tips are nice but not required since if it's a good idea then I'll get generation Buzz). Just leave a comment on one of my models or DM me. (Comments are preferred since that let's other people see that I'm actually fulfilling informal requests.) DMs are perfectly acceptable if your request is a bit out there and needs some image examples or something.
