New guy

Recently started dating a guy who’s fantastic! We had sex the first time and he didn’t come, we used a condom and have been using it for a while. His penis stayed hard for a long time. I tried to get him to cum but he said he didn’t want to because he was here to please me which he did! We’ve had sex a few more times and it’s like he doesn’t want to cum but he has. One time he even said I don’t know why you want me to cum. I asked him if I was doing something to keep him from cumming or if he just didn’t like cumming. He said you are doing everything right there isn’t anything wrong I just want to focus on pleasing you and I’m extremely attracted to you I just stay hard. Has anyone had this issue with their SO before? I really think he doesn’t like to cum or maybe there’s an issue. I just feel some type of way if he doesn’t cum. Plus we can go for hours and he stays hard. After I cum 3 times I’m done I’m not trying to pull all nighters lol. Just curious to see if any of you have had a similar situation before.
