I'm 15, and I have my first boyfriend (he's 16, almost 17, with a one year five month age difference between us). I really love him, and he loves me. Yesterday, we were kissing and ended up with us making out and him on top of me. He touched my leg, and my stomach and hip some, but didn't go anywhere near my privates. He's really sweet and polite and would never pressure me into anything, but we haven't talked about sex or anything. I haven't even asked him about his last girlfriend. I'm a virgin, and would like to stay that way for the forseeable future. I have nothing against sex in high school or before marriage, I just don't think I'd be able to handle it emotionally if I got pregnant or our parents found out or something. How can I bring up sex, and my boundaries, with him?
