He has a lot of female friends?

My boyfriend has a lot of female friends which is okay I guess but he mentions them a lot. Like he’ll say “my friend xyz… she …”. “Oh my friend is doing this”. “I’m helping my friend with abc she …”

It’s getting to the point where I can’t even tell if he’s talking about the same lady friend or a whole bunch of different ones.

Is this a weird thing to be annoyed about? What should I do?
