Save yourself. You are way to young to have sex. I had sex for the first time at 15, and have regretted it ever since.
The boys you like now you probably won't like in 3 years. You don't want to waste something this special, and a boy you'll barely remember after you're married with kids. I don't wish I had saved myself for marriage, because then I wouldn't have my first born son. But if I could go back the only time I wouldn't have taken back is the time I conceived him. I'm only 22 right now, so I'm young enough to understand what you're feeling. Also, the first time you have sex is usually awful.
