There would be only one real reason that you would say this:
A because you are jealous
B because you are gay, and really don't think he is hot
B is probably false, because in the time that I dated TWD at least four of my gay friends have thought he was really hot, which totally weirded me out
I'm bi (I think ), but I'm also 16 years old, which is why I'm not really attracted to somebody as old as TWD.
I do have a preference for girls though.
