I'm definitely not stealth. Though when my personal safety is at stake I am. But everyone at my work, all of my family and friends--they know my gender history. And it's fine. It's just an interesting thing about me, like that I'm left handed.
Also since I'm pre-op/non-op-ish it allows my girlfriend and I a lot of options in the bedroom, because we are both very comfortable with ourselves and very secure in our gender and sexuality(she's lesbian, I'm bi).
I've sometimes accidentally ended up in situations where I was stealth, and I hate them, because I'm always worried the person will find out and think I misled them, when that's not the case. But I do try to be as upfront as possible about my gender history. It's nothing to be ashamed of, in my opinion.
I also feel like I'm a semi-effective advocate for trans people, because I don't embody a stereotype, I'm easy to get along with, and am just in general a cool girl. Most of the time people who are initially upset about it, once they get to be around me, they end up loving me.
