Help?? idk if my man ejeculated inside me

kaashka
ok so on wednesday me and my boyfriend had sex , about 45 minutes later he told mr to turn over, he tried to put it in my but but it hurted soooo badly & it was a hot/burning feeling .. what does this mean??  then he told me to turn over again and he was doing it in vagina then about 30 minutes later he pulled out & i looked and he was nutting on my leg but before he pulled out , i felt a little warm sensation but i dont really remember exactly how it felt but im just wondering if he nutted inside me or not? and the nut on my leg i didnt wipe it off so could the nut on my leg find its way in my vagina?
