Im 15, and he's 16. Yesterday, my boyfriend and i were in a car and just making out..then we got horny and i sat on top of him. He took his dick out and i was wearing a skirt. I had shorts on and my underwear. We started 'dry humping' or him rubbing his dick into me, lightly for like 5 minutes. This happened when i was sitting on him and just moving back and forth. His dick wouldn't stay in the center it kind of went to the sides of my shorts for like a couple of seconds.. when we stopped i began to think if anything had happened. He said he didnt even ejaculate or become wet until after when he went to the washroom.. is it possible i can become pregnant.. im really worried ..............
