I just don’t have the credits to get naked men. Currently I’m producing around 3 videos per day, that gives me 1 suitable video (ie good enough quality) every 1-2 days. Male nudity has a much lower hit rate.
Breast size (rather like pubic hair) is VERY difficult to control. Mostly the AIs ignore you. The default seems to be large-breasted white women with almost no pubic hair. I use the term “average-looking” a lot to stop the usual super-model faces they like to create.
