For sure. I've seen that myself on a few occasions. I put it down to insecurities within themselves. That's something they've got to get there head around.
In my youth i was hit on, on a couple of occasions. Both times i felt a little uncomfortable about it. But politely declined on there offer even though they were quite persistent. They finally got the message i wasn't going to jump the fence. Just comes down to how you handle the situation. Back in the day, i even had a few friends that were Gay and/or Trans. One old bitch even used to kiss the fuel tank on bike with hot pink lipstick. She was a top sort, though. Good value..
In my books, everyone is accepted. Except for Pedo's..
