Is this even possible

Hey.So my period literally finished yesterday and today i had sex with my bf.We always do it with a condom,he pulls out when he cums and then we check the condom.Today we decided for him to finish on my butt.I was laying on my belly.He pulled out,removed the condom and something hurt in my vagina at the moment he pulled his penis out and i moved forward.He cumed on the side of my leg,near my ass cheek.I saw the cum it wasn’t near my vagina and my boyfriend is absolutely sure that everything will be fine,but i think that somehow,as he was cumming the sperm sprayed(fizzed,throwed)on my vagina.I didn’t feel anything but idk.What do you think?

sorry if there are any mistakes or misunderstandings but im not fluent
