Sex question

Im curious how long does your man last during sex? And how often do you do it? My guy and i don’t have sex everyday, but he lasts a while. Not sure if it’s because he jerks off a lot or what but he says it feels really good but with previous partners who said it felt good he couldn’t control it and got off like really fast. I don’t understand I guess. If it’s too personal you don’t have to answer…
