Harriet @107, the "sloppy" seems to refer to a misogynist notion that the semen from the last partner is still in the vagina. That's what makes it sloppy. So it's inaccurate because sex workers use condoms.
I don't think it would be unreasonable to expect a sex worker partner to shower after work, no more so than to expect a ditch digger or painter to do so.
If you have some notion that a night must elapse before sex is had, then you are being sex worker negative, because their jobs don't work that way.

Calliope @108, sure, we can learn and grow after age 25! Some of us, anyway. Others refuse.

@109. Bi. I was making a joke. (That is, @107 was a joke. @106 was not a joke).

Yes, it is reasonable to ask a sex worker lover to shower before sex.

I considered the narrow physical meaning of 'sloppy', but rejected it--since 1) people shower; 2) sex workers use protection, as you say, and 3) ... but that would be hot, right? Slightly crusty ridge, in the gay context; extra bit of lubrication, in the het? Nothing to complain about?

(The last part of this is sort-of a joke).
