I haven't heard the interview so I don't know what exactly she said in regards to doing hardcore scenes with men.
She has given interviews before and always gave the impression that she has an interest in fucking men on camera, however she has never specifically said she would. It was always something like, "Yes, I'd consider it" or "possibly" whenever asked about it. It was never a factual, "Yes it is going to happen".
Like I said, not having heard the recent Playboy interview myself, I'm not going to believe that she will do hardcore sex with men on camera until I see it.
Now she does have a personal collection of homemade vids she's done with BFs and hubby... it is possible she is talking about releasing those. But again, who knows for sure.
As far as being "cashed" or washed up.... HARDLY. She is still gorgeous and has an incredible body. Vicki Vette, Cheri Taylor and Teri Weigel all started in the porn industry at 37 years of age and Tylene still looks better now than they did then. So if she is going to do it, then I can't wait to see it.
