That doesn't mean you're not being open and honest about who you are, I hope you realize.
Every girl I've ever dated has known that I'm a gamer. Did I walk up to her and tell her the first time we spoke? No.
Doesn't it though? Aren't you conciouslly not revealing that information for fear that once they hear it they will reject you? I'm sure if you had a good job that would come up, but if you had an embarassing one, it wouldn't.
