This LoRA works better for INPAINT, but it does a good job on txt2img too. May break anatomy sometimes.
Trigger words (that sometimes Flux does not follow):
bush ***** - Shaved *****/vagina with hair on top / landing strip
butterfly ***** - *****/vagina with big lips
hairy ***** - Hairy *****/vagina, simple as that
shaved ***** - Shaved *****/vagina, in the style of cameltoe (innie)
asian ***** - Dark lips *****/vagina on a white skin woman
pink ***** - Pink delicate *****/vagina
Adding "showing her ass from the back" or something similar to show a rear view may work, as I trained rear view too for every trigger above.
You can combine more than one. Inpainting them to improve the result is a good option.
Use a strenght from 0.7 to 1.5, depending on your scenario. Negative weight put clothes LOL
