I'm not going to bash the guy. He may have led a hedonistic lifestyle, but he financed it himself. So far as I know, all his money was made honestly, not through any sort of theft. I'm sure many did not agree with his sexual mores, but as far as I know, he did did not drug women in order to take advantage of them, or use any other kind of coercion. He didn't go to them, they came to him.
As far as women feeling pressured to sleep with him while living at the Playboy Mansion? Pfft. It's called the Playboy Mansion, for God's sake, and not known for attracting young ladies of Puritanical values looking for a nunnery. If any woman says they got more than they bargained for "living" there, I say less "idiot" and more "liar". I would have more respect for those who sue a homeowner for shooting them during a burglary.
Porn? Anyone who considers the photo layouts in Playboy to be "porn" have clearly never seen porn. I have seen more racy layouts in my collection of 1930s hardbound National Geographics. A higher level of sensuality and eroticism was achieved by the Louvre long before Playboy was published.
