Girls, Should I be worried about my girlfriend going out with her friends to parties in college?

I just started dating this girl three months ago (the relationship just got serious) and she’s starting to want to go out with her single friends (one of the girls is taken). She’s in a sorority so I understand it’s like a thing to go to parties and stuff. I don’t think she’s the type to cheat but I’ve been wronged before. She always lets me know what she’s doing though so I feel crazy I’m worried. All I know is that she really enjoys going to parties and that frat boys get touchy. Should I be worried?
