I'm asexual and know a few other asexuals, but I don't think we really HAVE any stereotypes to fit into, lol.

On the other hand, I have met some bisexual guys (yes, they exist!) who act no different from their stereotypically straight counterparts, and I have met some guys and girls who you would swear were gay, but who honestly weren't.

I know a lot of people assume I'm bisexual upon meeting me for some reason.
