I'm 17 and scared for my life. My boyfriend came over n we kind of got into it n were down to underwear n boxers but he was "out" and we were basically dry humping for a while before it hit me how far we'd actually gotten and we immediately stopped before anyone could "finish" but I'm not sure about the whole precum thing on his behalf. This was all about 3 weeks ago and now I'm having stomach pains that no amount of pepto bismol can cure. He says its probably from the nachos we had the other day at a concert but it doesn't feel like that. I can't afford a pregnancy test, and I haven't had a period since I was 16 due to irregularity so I don't know how to know for sure. I know I'm probably being paranoid and if I am a good slap in the face would help a lot.
(also were both virgins and we both intend to stay that way until my 18th birthday)
