Rounds of sex help me out ladies 💗

Okay so yesterday I had sex with my boyfriend and we laid to cuddle and in five minutes he got hard again so we had sex again then like 15 minutes later he got hard again is that normal for men to get hard that quickly after? It's only an issue to me bc he is very large in size and likes being rough so maybe after the second time I'm sore and I know he's cumming after each timeÂ
