Not sure if I want to have sex yet

I'm not going to convince you to do it or not to do it. But think of it this way, you aren't sure if you want it yet. No one can really change that, you're ready when you're ready. If I were you, I would speak to my boyfriend and tell him I'm not ready. If he gets pushy/mean when you tell him then I'm sorry but he isn't the one.

You should only have sex when you feel ready and comfortable to do it. You're young and there is no need or rush to become sexually active so early. Us girls, especially being teens, sometimes can't handle the emotional and physical consequences of becoming sexually active at that age. Additionally, boys are very immature and tend to share these experiences with people who don't know what to do with that information, because of immaturity. I'd say wait. I recently lost my virginity and I am an adult. There is nothing wrong with waiting. If your boyfriend doesn't understand it, then he doesn't deserve you.
