The thing about this article is the fact that not once on the show did they ask if they were gay. I do think it wasn't necessary for Simon to tell that one guy to wear a dress....what was that all about???
However, with Zachary (the last guy), he was just asking for comments like the ones he got. While he does have feminine features, if he wanted to be seen as a guy, then dress like one. Don't go out wearing girls clothes. I believe he said (but not sure) that other people have wondered if he was a girl and how it hurt him. Again, if he didn't want to be hurt, don't put yourself in the situation that just sets you up.
