Saludos Vincent!
I agree with you. Pelt can also mean among other things to throw things at someone or something or to rain heavily. I do not wish to confuse Carmen so I will not pelt the pelt and be left with a pelted pelt that is soaking wet. I've probably confused her more so.
Another derogatory term in P.R. for a "promiscuous" person would be the word cuero.
One last item. In the last sentence I would use "de la manera en que se usa..."
