Hey, me and my boyfriend were messing around. I got on top of him (he had no pants or underwear on) and I had spandex and underwear on, and I rubbed him with my lower parts while wearing clothes. He ejaculated, and I quickly got off of him. I checked to see if I had any semen on my clothing, and I didn't. Two weeks later, I got my period on time. But he was still paranoid. So I took a pregnancy test (I believe it was one year old) and it said negative. He still was paranoid, so we waited and I got my period on time again. But he's still paranoid for some reason. And I'm not exactly the skinniest person, so I don't know if my stomach is getting bigger or not. Should he stop being paranoid or should we start worrying?
