I never had this issue. I'm guessing like that guy said, you need a patient partner who'll understand that the sex you have will, for a while, be a learning process for you.
You're probably going to have to learn how your pace impacts how prone you are to cumming (when to slow down, stop, etc). Tensing muscles in your legs can help, somewhat.
Practice makes perfect. Good luck finding a broad who'll be good enough to practice with.
