I agree that I dislike being stealth.
I'm not intentionally stealthy anywhere in my life, but I'm not the kind to make a big deal out of things. If it comes up then it comes up. If it doesn't then I'm not going out of my way to say anything. I don't like when people assume things about me either. I don't like people assuming that I'm a typical guy who has had typical guy experiences in life. Because that hasn't been my life, and frankly I'm quite a different person than I may have been if I had been born male in the first place, or had been born female and not-trans. I, like you, am proud of my experiences and of my trans-identity. It makes me queer, and I like that.
I am not, however, gay, so I can't relate to that part of it all.
I don't really mind coming out if its not in an awkward "coming out" manner. I tend to slip it into jokes. Actually ->-bleeped-<- jokes[me situationally making fun of myself not other ->-bleeped-<-s] are some of my favorites to tell. I like that I can brake peoples perceptions of ->-bleeped-<-s, and their thoughts that they could ever possibly be able to tell who is, and isn't, trans. I like that I can answer their stupid questions with a smile, debunking their previous misconceptions, and spreading real knowledge of what being trans is to the general population. I try to let no question be too personal, and try to answer every question in a "I've seen varied opinions on this ranging from whatever to whatever, but this is how I feel on that issue." format so that they don't get a closed mind that all trans people feel the way I do about everything. I figure if they meet someone who comes off as 100% male who they already have come to like and that is open about everything that they'll be more open to the information, and more likely to defend trans people and their rights in the future.
I also find that I'm seen as younger than I am. However, in my case its a matter of only a few years not half my age so its a little bit less of an issue. I also don't drink, so I don't find much annoyance in it at all.
