I've been taking a deep dive into the sources of my erotic thrills, and part of that journey included getting my hands on copies of the issues of Penthouse Magazine that my brother owned, which I used to steal from his room in order to educate myself. This letter was one of the ones that enlightened my young self that women could have sex with each other, that BDSM is a thing, that domination and submission can be pleasurable, and that it could be explosive.
