After getting over my childhood experiences, my brain suddenly found new "evidence" to prove my fear. When I was 16 or so, I was watching a porno and a guy bends over in front of the camera in tight jeans. I was aware that this was a man but took strong notice of what he was doing and said, "his butt looks nice there..." and thought it almost looks like a woman's butt. I started to panic about this but then realized that this means very little as well... I didn't start looking at more men's butts, I didn't have a realization at that time that I liked men, and this was an isolated incident. I may have seen the movie again a number of times after and took notice of him, but it was never a big deal. In fact, I always found it odd that I would take notice and shrug it off. I also reminded myself of "the yoga pants prank" that men pull on other guys (do you know what I'm talking about?).
Then I met my friend near times square and oh boy... Saw men's butts everywhere and I wanted to scream. One guy was really feminine and wore tight pants and I am starting to believe I like that.

Men's butts have always existed... have I just never noticed them before and never realized I like them until the age of 22? I only started realizing women's butts at the age of 14 because of my friends!!
