He Can’t Get Hard 🤦🏾‍♀️

So me and my dude have been together on and off for 3 years long distance and we’ve always had a lot of sex. Lately he cant seem to keep it up. He’ll get hard go in and then last about 2 minutes then can’t get it back hard the rest of the night or the next morning. I assumed it was me but he said when he’s tried watching porn its still not getting hard for him. Anybody ever had this issue ? Idk what to do!
