What should you do after an orgasm?

Ok so I'm not new at having sex but I am new at orgasming, it took me many years to figure out how and then to figure out how to during sex. Now that I'm able I'm not sure what comes after, should I lay there and soak it in? Or do I immediately let hubby finish himself off? I notice when I masterbait and get the big O the feeling lasts longer, I don't know if that's because I'm not still stimulating myself down there whereas I usually let hubby finish right away or if it's because I'm less In my head.
