boyfriends sex game weak

It's almost depressing thinking about having sex. It doesn't feel that great. I mean it's okay buttttt it needs work. He last for only 5 minutes every time if not less and even eating the 🐱 doesn't feel good. I just lay there. Before him I loved loved loved sex and couldn't get enough and I miss that feeling but Idk how to tell him how to fix it. I honestly don't know what I like just that I like it. Is it possible to get better?
