I've been seeing this girl for 5 months. She's 18, I'm 20. We met at a party during the school year. I just became exclusive with her about a month ago. Now that the school year is over she went back to her hometown near the city. I've met her parents and recently her girlfriends. She's wanted to introduce me to all her friends including guys, but I act like I'm not really that interested. Anyways she's throwing a house party at her house inviting her girlfriends and her guy friends. By guy friends I mean they were part of her group in high school but they don't really keep in touch as they don't text. Anyways her friends and her have mentioned I'm and upgrade over the guys from her school. She lost her virginity in university.

The question is what should I do at this party because her guy friends are going to be here which include guys she's done stuff with. I've seen pics of her and her friends in high school and I'm way better looking than most/all. Plus it's a pool party and I'm ripped, when most of them have beer bellies. They also wear clothes like American eagle, Aeropostale...I just know I might be in a position where I don't know anybody and I'm not going to follow her around like a lost puppy while she speaks to guys/girls. She would never do anything, but I feel like I'm going to be tested many times here.

What I was thinking of doing was to just become the life of the party as I'm very extroverted. I was also going to ignore her, but make it look unintentional. She also told me 3 of her friends said I was really hot and one of them wouldn't stop staring at me when she introduced me to her friends.
