Potentially controversial take
@Motodrachen Don't try so hard? Usually for cishet guys, comes loosely down to "cishet girl", "dude", "everything else". He might not understand that there's way more subcategories to that third category but most people will respect it. Let him know your preferred pronouns and work with what you got.
Unless you're trying to work out how to explain it to someone green to the concept. Then I don't begin to know enough to know how to do that myself.

@BalooUriza It's less the pronouns and like...
I just wanna tell them outright that I'm not a Guy, don't hold me to that standard and we'll be okay.
I just can't deal with the implications that I'm not living up to some ideal of masculinity and I should be ashamed.
re: Potentially controversial take
@Motodrachen Just say it like that. When it's appropriate to real talk without potentially publicly embarrassing him, just say it like you explained it here.
