This took me quite some time to answer, and for that I'm very sorry especially given the short response.

I don't interact with other trans men in real life. I haven't even (conclusively) met another in my local community except my boyfriend. I've given the knowing smile and nod at other binary trans men at Pride festivals but that's been it for me.

for many reasons, my IRL social life is very cold right now. I keep people at an arm's length, and I really havent had any close friendships in a few years. in the past year, I've only seen other trans guys when I was working with them. pretty sad tbh but it's a really complicated situation to fix right now. and I cant really remember what it used to be like

I don't really socialize with trans men, directly. Not by choice or anything, that's just how it's gone thus far. I know one trans guy in person, but we met in a support group and largely see each other in that context. But then online, I don't actually talk to anyone one-on-one. It's more generalized void-shouting and responses to void-shouting, so I'd hesitate to consider those "conversations," which unfortunately leaves me with a trans guy shaped hole in my proper social life.
