I don't listen to Barbra/Liza, or most pop music or whatever. But I listen to some. Its fine. I listen to other things. I listen to metal. I listen to a little country. I listen to a lot.
I don't dance shirtless in bars. In fact, I've never been to a gay bar or gay club. Its fine. I might do it later. No big deal.
I don't fly a rainbow flag. But I support it and its idea. I am open about my LGBT+ (yes, including T, trolls) support.
I don't get my taint waxed, but I do, once every few months, trim or shave myself for comfort reasons because I can get a little too hairy, eventually, for my liking. But it isn't very regular.
I do watch my carbs a little, and my diet in general, because I want to continue to be lean enough as I also gain muscle bit by bit. Didn't know this was such a gay thing.
My voice can be silly sometimes, and maybe softer than the masculine straight ideal(?), but most of the time, it is 'regular' and deeper and most who attach to stereotypes can't believe I'm gay from it.
What is gay lifestyle? We can specifically define it, I suppose, but almost no gay men follow it exactly. Myself, I'd consider myself closer to the gamer 'lifestyle' than the gay one, but that doesn't mean I need to hide from the latter or consider it alien to myself. R176 has got it, IMO. There isn't a need to fixate on exact definitions of a lifestyle - it even defeats the point of the word. Style, not law or cult or whatever. Just doing what you do.
Its been a task (albeit a mostly easy and passive one for me) to simultaneously show to straight people (who separate gay and straight a lot) that I can often be just like them in aspects, while showing gay people (who separate gay and straight a lot as well) that I often be just like them in aspects. It isn't quite so annoying as for those who are biracial, but yeah, there's always 'educating moments' with people where I have to let them know that I am myself, not just 'a gay person' or 'like the straights'. Just myself, with attempts of love and understanding for those of either 'side' (which I find often hard to regard as such).
Is that assimilationist? Maybe, but I also often respect straight people who sometimes don't want anything homosexual near them, and gay people who want their gay culture to be entirely its own thing. I just dislike strong enforcement of their opinions on others. I'm not for segregation 24/7, and assuming that a gay life means 'gay lifestyle'(tm), can be part of that segregation. Its great to make friends with those like you, but I find it *ultimately* better to make friends everywhere whenever possible, not *only* because they fit a checklist.
I enjoy Lady Gaga (really) over working on a car. Oh so gay of me. But wait, if you're interested in working on cars and teaching me how they operate, and you're friendly about it and open to teaching a newbie, then..lets go! Then later on, I can take someone's invite to see a Lady Gaga concert (hypothetically; I haven't actually gone to one), or maybe even invite the car-working friend, if he seems remotely interested. Or not. It shouldn't be a big deal.
