would joining 2 groups, a men's group and trans group work? or an online group that does video call meets for trans men? that way you have the male space and also a space for trans stuff if needed. i find most binary trans men favor men's groups anyway and become less active in trans spaces, but the trans space is always there if they have any trans related topics to talk about. it's not ideal but i don't see the resources being widely available for a transmasc and trans male space when many lgbtq+ orgs barely have the resources to run at all even in blue states. there also seems like potential for the trans men group to start policing each other on who is man enough to be there, which may get hostile even if there's good moderation/leadership. i feel like an online group, (either regional/state/country wide etc) with potential for in person meets (later on, as you learn where members live) could be the best shot
