How to stop one and done?!

I swear my husband has sex once And he's just over it! I want to keep it going and I'm trying all this stuff and it's like he's sooo into until he cums! Then he's just like well I'm hungry I'm going downstairs! Like really? I'm like begging for more and you want food or to watch tv! It's like a switch flips as soon as he's done!! It makes me so freaking angry!!
