16, going to first teen rave?

Three of my friends invited me to a rave this Friday. It's for ages 16-25 I think, mostly high school students go. My friends all went to one in march, and one of my friends, Amy, said that the other two went off with guys and danced and made out with them the entire time so she was basically by herself. She begged me to go with her cuz she doesn't wanna go with just those gwo, so I'm going this time, so it'll probably just be me and Amy. I've never had a boyfriend or had my first kiss, so I don't want it to happen here. It seems kinda stupid if I look back ten years from now and say my first kiss was with some random guy I didn't know at a rave. So i don't know what to do? Should I reject any guys that ask me to dance or whatever? And I also don't know where I'll put my phone! I have an iPhone 5, and I can't loose it! I'm going to wear shorts but none of my shorts have zippers or buttons, so how about if it falls out? I'm not sure what to do about all this, id appreciate any advice!

Don't drink or do drugs and say you have a boyfriend if you don't wanna do something stupid. Keep your phone in your bra but its probably best just to hold it cause those things get pretty squishy. Or even don't bring it.

My advice: don't go. Sure, your friend may want you to go, but what happens if there's drugs or alcohol and you you're caught with it? I say you should find something else to do that face the risk of loosing your iPhone, doing something stupid like drugs, or taking it the next level with some random guy and ending up losing your virginity. That *** actually happens, and it shouldn't happen to you.

Raves are simply an excuse to make out in most cases, It is what people are there for so it si really stupid to go when this is not what you want - frankly the idea of a 16 year old going to a rave with 25 year olds sounds predatory
