Okay. So me and my boyfriend try to stay away from having sex until we are out of high school at least. But we do other things like "dry humping". Well, a couple weeks ago, we were making out, standing up, and he pulled my pants down. I still had my underwear on.. And he pulled his down. His underwear were on. Then he basically pressed his penis onto my vagina but we had underwear on.. And I'm sure he didn't ejaculate? If he did ejaculate, could I be pregnant?
