How many times you've been mistaken for the wrong gender here?

A bunch of times honestly. Many first impressions here involved me being the Opposite Gender and not gonna lie, it was kinda fun messing around like that at times XD Pretty sure there are still a few around who think that !!!!

I mistook a few others but never got it myself

I think once or twice?

More often than not it's my sexuality (or lack thereof) that gets mistaken.

Hmm Well, I don't think I have to my knowledge. In case any of you didn't know well I'm a female lol
