I'm with ya 100%.
I remember letter after letter about sex with amputees from those days. Not that there's anything wrong with that -- differently abled women need love, too.
I always knew I liked soft things like fur and girls with long hair, but it wasn't until I saw the Penthouse Letters about hair fetishes in the mid-1970s that everything came together for me.
They also had some letters about light bondage that got burned into my sexual psyche.
