What should I do?

So I'm a 16 year old from the U.S. and I made a tiny public art discord server a few days ago. A 23 year old Lebanese guy joined and friended me and keeps asking for my name irl and for me to speak in the voice chat. What should I do? Am I just overreacting? He seems really pissed by the fact that I use a male name for my discord tag and he doesn't want to use it since I told him I'm female (I'm actually transmasc, but it shouldn't matter anyway).
