yeah so nothing is universal with trans people, so it's always good to have a chat / bring up what you're wondering before you bone

usually if I'm with someone new who is trans I like to ask what they like their bits called (maybe what some people might call a clit is actually a cock now for example) and what makes them feel best and most comfortable, anything that makes them feel uncomfortable etc. I think it's also worth asking how they feel about their chest since lots of trans masc folks dislike it being touched or even having it bare.

might feel like an uncomfortable or awkward discussion, but personally one of the reasons I don't like to fuck new cis people is because it always ends up with me having to lead a sex ed seminar, so it would probably be refreshing to have someone take the lead on respectful communication.

make no assumptions, tread politely, be a nice boy

hope you get strapped or whatever, godspeed soldier
