Questions?

So I’ve been talking to someone for a little over a month now and we plan on making it official soon(even though I️ tell anyone and everyone they are mine😍). They told me they were gender fluid at first and last night we had a conversation and he told me he has identified as transgender(ftm) for many years. It doesn’t bother me at all I️ like him for him not any other reason. But I’m scared of how my family or friends will react when they meet him. I️ don’t want them to say something stupid and scare him away. I️ realllly like him and haven’t felt this way since my ex husband really. And I️ don’t want to lose him. Any advice on meeting the family?
