There was a thread titled "Letters to Penthouse" in the Lounge area of the General Discussion Forum on this site. Unfortunately, it saw activity only on one day, namely March 17, 2013. It had nine posts and has long since been archived. Since I wanted to respond to the things written there, I'm starting a new thread here.
The reason this is of interest to people here is that Penthouse Magazine was the only erotic magazine aimed at straight men that dared broach the subject of man-on-man sex. At one point, one of Penthouse's slogans was "For the Practicing Heterosexual." I heard they were considering changing that to "For the Practicing Bisexual," but they never actually did. Penthouse began publishing such letters in 1978 (if memory serves me correctly), and they petered out around 1989 or 1990. However, there was an entire family of Penthouse publications. Besides Penthouse Magazine proper, there was Penthouse Forum, Penthouse Letters, and Penthouse Variations. Discussions of gay male sex may have continued on in those other magazines well past 1990.
There were actually a lot of kinks in the letters to Penthouse that I found arousing besides gay male stuff. Having read the forum rules, I know some of that stuff is out of bounds here, so I'll avoid it. Other things I'm not sure about, but I'll avoid that too, unless the moderators give me a green light. Explicitness is forbidden--but does that apply solely to photographs, or to verbal expressions as well? Pedophilia is forbidden, but does that cover teenagers having sex with each other (which is legal in most states--but not all) or adults having sex with teenagers (which is properly termed ephebophilia, but most people mistakenly refer to it as pedophilia)? I hope some moderator will see this and clarify this for me because I definitely want to stay within the boundaries drawn by the rules. Another question is, can I copy out some of those letters, or would that be considered copyright infringement? And if it is a copyright issue, can I retell the story in my own words?
