Really uncomfortable 😷

So I had sex with my boyfriend last weekend (it was his first time and it was my second) the sex was good and he kept fingering me aswell but he went really deep and it hurt, he understood so he stopped but since we had sex I've been so sore and itchy downstairs, and rather smelly, it's like discharge😷 I know 1000% it's not an sti etc as it was his first time and I've always used protection in the past, could this be because he was abit too rough fingering me or could it be because I hadn't had sex in 14months before me and him had sex? We used a condom and lube so could it be that I had an allergic reaction to that?
