Im not sure. I think that those photos are pretty attractive but pretty obviously gay (no offense).  However, I was friends with a girl until I knew she was a lesbian when she walked around wearing a shirt that said, "All the cool girls are lesbians," with some rainbow pins attached, but most people still thought she was straight. That is a clear example of how it doesn't really matter how obvious you are, people are just that oblivious so you have to be more vigilant.
