This sounds pretty normal and there are many ways to handle it. Try masturbating a couple hours before intercourse, it should make you last longer by "Empty the chamber" or when you are close to climax stop and maybe switch position to give you time to gain composure or have her give you oral. There's also the squeeze technique which helps if done routinely.
