Answers please!!

So the other night I had sex with a dude I've been seeing for awhile .. and outta all the other times he took forever , I got so aggravated that I just made him stop cause he won't nutting 😂 but I'm starting to feel like he accidentally nutted in me and is to embarrassed to tell me ? Cause I just never y'all 😭😂 well I asked him I said did you nut in me cause if you did I wanna get a plan B and he told me he didn't well anyway , before all that and this is what made me think he did accidentally nut is because he randomly just said " he was gonna put his kids in me" like.... ? And the next morning it was constantly feeling like something was coming out of my vagina!!! Am I'm tripping y'all ??
