About two weeks ago, I had sex. We took a shower together beforehand (did NOT have sex in the shower) and he picked me up and the tip of his penis brushed up against my vagina for a second so I had him put me down. We had sex for 15-20 mins with a condom and he didn't finish at all. Stopped cause he was hitting my wall. My period isn't due for 3-5 days and I'm getting on the pill next Monday... Do I have anything to worry about? Like Precum? He said he hadn't came since the night before and had urinated since.
