I spent a lot of my formative years (see: high school and part of college) fighting to differentiate myself from the "norm." I wasn't that girl.
I wouldn't tell people until I knew I could really trust them (which, for me, is a process that could take years) that one of the first CDs I ever owned was Shania Twain or that I actually liked the movie Legally Blonde. Those were things I never told anybody about, because somehow in my mind they defied the image of myself that I had built up as this tough, sassy, queer chick who sweated along with the men on summer crew and fucked on the first date if she felt like it. I saw it as two completely different sides of myself, and it was damaging to admit those other preferences. They were going to tarnish my reputation or some such bullshit.
As difficult as it was to come out as "different," it was an entirely more difficult process to re-acknowledge the "mainstream" parts of myself after I had the whole "being different" thing settled.
I've reached a stage now where I'm pretty unapologetic about myself regardless of what aspect of myself I'm talking about. It's stopped being a contradictory thing that I feel like I have to excuse or somehow apologize for. "Oh, yeah, I get my nails done on a regular basis but I also really like eating bacon cheeseburgers." As if those two things are somehow mutually exclusive, and liking one makes it completely impossible for me to like the other.
