Do you struggle to talk with groups of people in a social setting?

I’m ok I’m one on one conversation, but the more people you add the harder it becomes to keep up with the conversation. It’s not even about being nervous, I can talk in front of a group of people. I have no problem with public presentations or leading a group of people in training. when it’s a social conversation, Idk what it is but it’s so hard. I fall behind and when I do contribute my comment is out of sync with everyone else in the group, as in the conversation has already moved on.
