LGBT+ teachers- do your students know?

Going into year 7 of teaching middle school and I'm bisexual. I always sit on this awkward fence of whether or not my students know? If I keep my mouth shut, I can stay in the closet very easily. I'm married (to a man) and obviously my dating history doesnt come up with students. But there are some times when it feels like lying by omission, like when I explain to a kid why using "gay" as an insult isnt ok or if a kid comes out to me. I tend to play it like I'm just an ally but it feels...inauthentic.

Just wondering how other people deal with it.
