Some linguistic confusion

I looked up the dictionary definition of "skanky", and Wiktionary has this to say:

skanky Adjective (comparative skankier, superlative skankiest)
   1. in the manner of a skank (disreputable woman)

skank Noun (plural skanks)
   1. (pejorative, slang) A lewdly unattractive and disreputable person, often female, especially one with an air of tawdry promiscuity.

Now tawdry means "cheap or gaudy", which suggests that placing too low a price on one's promiscuity is a bad thing. But assigning any price to sex makes one a whore, which is also considered a bad thing. So, which kind of promiscuity is the good kind?

And doesn't this make the phrase skanky ho a self-contradiction?
