Way too fast

Me & my husband have been married almost 3 years and have been together for 5. We are both 22 years old. I have a really high sex drive and my husband has always been able to keep up with me. Until just recently, sex only lasts about 5-10 minutes. He hasn't been able to hold on. And I'm not feeling satisfied sexually. I'm starting to get frustrated. He says it's "just too good". But this has been months of the fast ejaculation. When we do have sex I try touching myself to have an orgasm but I don't have enough time to even do that before he whispers "I'm about to cum" 😒. We don't even do multiple times in a row. He usually goes right to sleep. We normally only have sex late at night because we have an active 10 month old. I just don't know what to do. I love him and I would NEVER cheat on him. I just want to get back to the sex we used to have.
