If he didn't ejaculate in you there isn't too much to worry about. BUT DO REALIZE that if he doesn't use a condom his precum can get you pregnant! If you haven't yet... you should try to find a teen clinic in your area and have your boyfriend, a friend, yourself or a relative you trust take you there to get on birth control. If there aren't any teen clinics you should go to a gynecologist to get on birth control. I believe you have to have parental consent/ insurance to get on birth control at a gyno I'm not sure. I went to a teen clinic.... you would go- get a physical- take a pregnancy test and they would give you the pill (or there are other forms of birth control) and a bag of condoms so I would be protected- all for only like 11-20 dollars! Anyways, you need to get on birth control to prevent an "unplanned" pregnancy. I was on birth control (but had been on antibiotics--- which basically "kill" a birth control pill) and my boyfriend (now husband) and I had unprotected sex and I got pregnant! So be EXTREMELY careful! Also, if you miss your period next month you may want to take an at home pregnancy test.... also you can take one about 2-3 weeks after you and your boyfriend "fooled around" to help clear your conscious!! Good luck!
