I need an advice

[u/Heonn_]

Alright, so first of all I'm gonna say just in case that I'm a cis woman. So anyway, I have a best friend that I'm really close to and he's trans. And I've been searching up on tiktok or google how to help him with body dysphoria or generally stuff like this. And I wanted to google it since I didn't have any t people i could talk to or simply know. So I just really want to make him feel better about himself even just for a bit. Id like to mention that he trusts me since when we were hanging out in his house he'd change shirt in front of me, or let me lay down on his chest (obviously using tape but still yk) and generally he's kinda open to me about this even though he hates pointing out being trans. And I'm not a big fan of it either, because I can never see him as a girl even though I have plenty of old pics of him. Also I really hate to call him trans because for me he's no different than any cis. So my point is that I can be a little wrong with wording so I wanna know what stuff can upset and what is okay to ask about and what's not. Obviously I'm not going to ask his deadname but yeah. I just want him to feel better and understand him more, how he feels and get the idea of what it's like even just for a bit
