This is a bad theoretical question. Because why would they be there unless they were looking for a man?
A better question is: If a CD goes to a bar or party and is speaking with a group of men. Then the answer I would give is.
My answer is no. Unless one of the men gets you off to the side and is really hitting on you. Then I would inform the person. If that does not stop them well where you go from here is your business......
