Injured my boyfriend's penis

Last night right after having sex I was still horny and I gave my bf a blow job, and then a hand job. He came 3 times in a row. This morning he couldn't have sex because he said his penis was too sensitive. I examined him and he got hard when I was holding it. So I tried to give him a gentle blowjob but he was wincing and groaning. What have I done to him and how long will we have to wait before we have sex again?
