So around my ovulation, my boyfriend and I were doing stuff, he ejaculated the first time, this was from hand simulation, as we have never had full on sex before . We waited around like 30 minutes doing whatever, and then we did stuff again and this time we were dry humping, he has compression underwear and basketball shorts and I had thin Victoria's Secret leggings on. He did not ejaculate but I'm scared that some pre-cum has seeped thrown he and onto my thin pants can I be pregnant.
