Do You Use Male Porno When Doing It?

I suppose we're all interested in not only how to do it better, but how the other half does it as well! A guy friend of mine has a question for the gals-to settle an argument:

As you know, guys have for decades used porno margazines like Penthouse and Playboy to masturbate by, with the advent of VCR's, porno movies, the more recently the internet, porno sites-showing beautiful naked women.

The argument you can settle is over Playgirl magazine. He contends it is now mostly read by gays, while others say that while that once was true, it's not anymore. And, to a larger question, do you gals/girls/women like to masturbate to porno pictures of men, like guys do in reverse? Like to see as many responses as possible! Thanks
