I don't really see it? People have different kinks... I mean just in this hobby pse, cim, rimming (aka licking a strangers butthole), and to lesser degree swallowing is normalized and even itemized (see LA org ads). Fluid play is something that isn't really completely out of the whack.
Hell, Greek and cof is usually something that many, many indies do. I personally don't think kgirls would care that much if they were guaranteed nothing would go into their hair eyes or makeup. At least not those who rim ardently swallow and do other comparable stuff.
Just my two cents
