Is It Okay for Girls to Go Out to Clubs?

If your girlfriend acts single, she's not your girlfriend. Would you vote for a politician that likes to spend all his free time surrounded by lobbyists for organizations that want to steal money from you? If your gf is purposefully dressing in ways and going places that she knows will provide her with constant sexual attention from other men, it's not "insecure" to wonder if she's trustworthy enough to be your girlfriend.
