I must be WAY out of it. There is no way that I would have even contemplated allowing my daughter to have an overnight with a boy. you are too young for sexual activity, and too old for mixed gender sleepovers. - I suggest holding off on the sleepover for at least 4 or 5 years.
Sure, if you like. Wear what you're comfortable in, like jeans and a t shirt, and that'll be fine. Take a small bag of stuff that you need with you - pajamas, toothbrush, and anything else you may need. Have fun!
i think you're far too young to be sleeping over with a guy, but yes you bring your pjs or just keep the clothes on that you wear when you get there. be clothed at all times!! bring what you would normally bring when you stay the night with someone. (toothpaste, deoderant,etc.)
Slightly off topic but please be prepared to what your going into. He might want sex and if you don't want to don't let him pressure you and/ or leave. If you want to PLEASE be safe. By that I mean make him wear a condom because you do not want to be pregnant at 14. Also do your parents know this sleep over is with a boy? Make that clear to them.
A sleepover with a guy at 14, is this with a group of people? I'm trying to understand if this is a cousin or family member. Wow is all I have right now. I would never let my daughters do this, I don't think times have changed that much since they were your age.
