Answer He may be inexperienced, he may not be able to control himself so there are a few ways to avoid this. Try giving him oral sex before he pentatrates you, or a hand job because if he cums once before entering you, he won't cum so fast. Most men take half an hour to a full hour before the can cum again, even the younger guys can't ejackulate that quickly if they have an outlet before penatration.
There is always some chance, however small.
It always depends on the person. Most men take around 6 to 7 minutes but like I said it depends on the man
