I had discovered purely from curiosity in the bath what the inside of my butthole was like, and one day I was daydreaming about an android that chould change between male and female so I could find out what it felt like to have android dick in my butt, when it hit me like a ton of bricks that men also had dicks and that I wanted to know what it felt like to have a man’s dick in my butt.

I was shocked

Up to that point I had no idea I might be in the least bit gay - I was into girls. I had felt a bit funny seeing tarzan lying face down on the ground, but thought nothing of it. It was years later I understood the term bisexual. Might have saved quite a lot of confusion in the intervening years.
