Should I go to the party? (first one)?

im 14 and i live in RI and my friend who is also 14 but looks a lot older, he has facial hair, very deep voice, and is deep in puberty, goes to parties all the time. he smokes a lot of weed, and claims to have a lot of . i smoke weed occasionally, maybe once a weekend, and i have only gone as far as once but i haven't made out with a girl (weird, i know). he says the party is at a rich family's house on the outskirts of providence and he was invited by a 19 year old. he says most people that go are 16-18. im really nervous about going because ill look a lot younger than everyone else and they will be drinking and i dont like to drink, so pretty much im afraid i wont fit in at all except for having a friend there and getting high. he exaggerates with a lot of stuff like trying to overprice weed and saying how he got tied up and ****** by 2 16 year olds until he came more than 50 times and how he wanted to die. i have a feeling there wont be as many people there as he makes it seem like but still im nervous because of the age difference. o yea, and he said "if i find a girl with a little sister ill hook u up". that makes me feel like a little kid. im alright at rolling joints so maybe ill have something to do there ahaha
