My boyfriend and I dry humped yesterday and we were fully clothed, he even tucked his shirt in.
After we dry humped we checked his underwear to see if any pre was there and we saw a spot.
He then grabbed the top of his undies and flipped the label over to check if any went through the top, and we didn't see any from the naked eye. Although when he touched the sides he later on went and massaged my cagina with his fingers, could this cause pregnancy if touching his undies cause some pre to go on them?
