As I can't bind anymore, I don't pass all the time, so technically it wouldn't be possible for me to "go stealth." Even if it was, I'd still live the same way, though.
I don't mind people knowing I'm trans. That's not a big deal to me. I don't like having to explain it, and I occasionally have bouts of paranoia about whether one person or another has somehow found out what my girl name is--which, to my dismay, is still my legal name til I get $350-ish to change it, and is one of the girliest names in existence--but other than that, I'm happy with being openly trans.
During my teenage years, I had to hide a lot of the major things about myself merely to avoid getting kicked out of the parents' house--my gender identity, my sexual orientation,* my religious beliefs, etc--so it's quite freeing and nice to be able to proudly say, "Yeah, I'm trans," or "Yeah, I'm gay," or whatever else.
The more I can tell the truth about myself, the better I feel. I wouldn't trade that for a life where people assumed I was a cis-male; sure, it'd be nice to never have anyone question my masculinity, but I'd rather just be open about myself.
*Went through a brief "omg I must be a lesbian" phase before I realized it was my gender that was making me feel weird about dating guys, not my sexual orientation.
