Hi, My Boyfriend And I Had Sex Yesterday Morning (having

Hi, my boyfriend and I had sex yesterday morning (having not had sex in a while due to my period). We stopped to change position and I noticed the end of my boyfriend's foreskin looked a little red and swollen on one side. He said he'd been a little uncomfortable in one position prior to that but hadn't wanted to stop me(!). So we then stopped and I made sure he cleaned it properly in the shower afterwards. However, this morning it's quite swollen and the skin looks a little scabbed - it doesn't hurt when he urinates but it's uncomfortable if he tries to pull the foreskin back at all. The scabbing and swelling is on the end of his foreskin rather than the head of his penis. Thanks for any help!
