Sex(advice or help )

Me and my boyfriend had sex today it was nice I enjoyed it but it was probably like 20-30 minutes but I mean he was a little rough not too bad but still very enjoyable it’s been about 2 hours since then we cuddled afterwards and I showered but I am feeling some like throbbing and a little pain is that normal ? I mean it did hurt at first when it was going on but it was great.
