Aww, men aren't so bad... OK, the creepy ones have to go, but if you give off a gay guy vibe, that's what you will attract. I remember my andro phase on the train...
The best thing to "wear" to signal that you are a lesbian is a girlfriend.
If you present female in public, you will likely stop attracting gay guys. OK, they won't leave me alone now, but they are seemingly no longer interested in me as a potential lover.
