Re: Hmm im scared, lol
Do not have sex under any circumstance. Simply put you and this girl are too young and not mature enough to have sex. You are just kids yourself and having sex risks you becoming a father and having a baby at 14 or 15 years old. That is something you do not want to end up in.
When you are a young teenager you need to learn to have self-control and don't give in to urges to have sex. It can cost you an STD or child which are consequences that can affect you for the rest of your life.
She's obviously is in casual sex so you have no idea what kind of diseases she may unknowingly have so you'd be putting yourself in a major risk having sex with someone with multiple partners.
Underage sex is not worth it. Sure people in your year may have had it (but do note that people do lie), but at the end of the day, it's your life and you're responsible for your actions, not anyone else.
You should wait to have sex until you are older until you're with someone who loves you for who you are, not for the size of your equipment.
You are too young - do not have sex!
