I loved those Penthouse Letters, especially the bi sex ones. Beat off many times to those stories!!I really loved Penthouse - what was then, very explicit for a widely available magazine, and would masturbate to the lesbian scenes in their pictorials. Then I started to read the "Letters" section and those stories (some of which, I truly believe were written by staff members) are what got me into reading erotic literature. I could edge to those for hours and conclude with a great copiously sperm-filled orgasm. During those years, I hadn't considered male bisexual encounters before reading about them in the "forum". They became some of the most sought-after stories for my masturbatory sessions. "Turned"? No. "Opened up to"? Yes. "Broadened to include"? Absolutely.
