No. Hence the term "man whore" was invented as the male equivalent. Plus you can always get a good idea of how regular young people define a term:

I'm old enough that when I learned what "whore" meant it was only in reference to a female prostitute. "Gigolo" was the term for a male who had sex for money, but it's never had the same negative connotation as whore.

Sort of. You might see a headline that says "CONGRESSMAN CAUGHT WITH MALE PROSTITUTE", but never "CONGRESSMAN CAUGHT WITH FEMALE PROSTITUTE"--it's one of those concepts that is understood to be female by default.

I'm trying to think which gender i'd guess if I read: CONGRESSWOMAN CAUGHT WITH PROSTITUTE.

I honestly think i'd guess male prostitute.

Yes, but it is insulting to the non-whores. Its also insulting to non-people. We need a gender neutral, species neutral, personhood neutral word to describe "corporate whores".
