Definitely think this thru Once you lose your virginity its not something you can get back. You are giving a part of yourself to someone and taking on a part of them in a very delicate way. It most certainly isn't something you want to give to just anyone. I know that it is very difficult being a virgin in highschool. I kept myself until I was 18 and married and I can honestly say its the best descion I ever made. Yes peer pressure is a hard thing to put up with but, Anyone who is trying to push you into having sex with you dosent honestly care about you .They will only take what they want and run. Don't let that happen to you be strong and stand tall. It's better to be a virgin than to just give such a precious gift to someone who dosent truely love you. Hang in there sweetie.
Don't ever let anyone pressure you into doing something like that because you will probably regret it if you just do it with someone that you don't love and trust
Losing your virginity is a very big deal. I'd not squander that first time on some guy in high school that isn't someone you love and loves you and isn't going after sex with you. Peer pressure to have sex is no reason to have it. I'd hold out for as long as possible and truthfully, many more guys will respect you for that. good luck
