Me and SO kinda sorta had sex. We used a condom. I checked them after wards ( put water in them to make sure there wasn't any holes) he didn't cum. He had precum before when I was giving him a hand job.. I still get worried, even though we used protection and asked him if he cummed at all today, and he said yes. This morning and we had sex at night. So he obviously used the bathroom throughout the day, and I made him use the bathroom before us having sex. So should I be worried?
