Depends on the theme and where you are gaming I suppose. I’ve thought about a she-barbarian army based on Maidenhead Miniatures. It is on my to-do list, but not near the top. Something Casanova-esque on some Lace Wars table wouldn’t bother me, provided it was done with some subtlety and wit. Naked slaves in Egypt or Minoa – no big deal. Even the Bayeux Tapestry has some ‘naughty bits’, embroidered by English ladies so it is said.
Neither a big passion nor upset for me, if we are talking about display of skin. There are some BDSM figure lines that look like they were designed by a sex offender on his twenty third year in solitary. That is something else entirely, and needs to rise to the level of art or GTFO for my tastes.
