I sort of had that happen to me. In middle school, someone started a rumor that I was gay. This was early 90s, and I was young, so it bothered me. I was new to the district, and didn't have many friends, and being called "gay" was something bad in my mind.

But then I suddenly had a bunch of friends who were being really supportive. Some were gay, some were straight, but everyone just encouraged each other to be who they are. I learned a lot from them about acceptance and being myself. Years passed.

But none of them ever asked me if I was gay. Anyone that asked, I would say "no, I'm straight." Apparently people thought I was in denial.

But then I asked a girl out, and she was like, "Wait, but... Aren't you gay?" The look on her face is seared into my subconscious. It was a mixture of confusion, betrayal, and contempt. Like I had been pretending to be gay to worm my way into her friendship, all the while being a lecherous creep waiting to strike.

Also it turns out, one of my gay friends was working up the courage to ask me out. It was the talk of the lunch table, except they had been keeping it from me because they didn't want to embarrass our friend.

So I had to go to that friend and explain that I liked them as a friend, but I was not attracted to men. He then claimed that he wasn't interested in me, which was really fucking confusing. And then I had to clarify to everyone at the lunch table that I was, and had always been, straight. Which is weird enough, but I had also now rejected one friend and creeped on another.
