The only thing that I've really done consciously is try to walk slower and more casual, since I found out that apparently it's a gay trait to walk fast or something (

), other than that I don't really have many of the stereotypical traits, I don't ever use hand gestures, never have, and I have a reasonably deep / normal man's voice.
The only other thing is I'm very private when it comes to my music taste. I just don't tell anyone what kind of stuff I'm into. And for the most part it never comes up, so it's quite easy to avoid.
