Follow these simple rules for building up your sexual endurance.

1. Squeeze

If you’re overheating during sex, stop and squeeze right below the head of your penis, focusing the pressure on the urethra—the tube running along the underside of the penis. This pushes blood out of the penis and momentarily represses the ejaculatory response.

2. Sexercise

A Kegel is an exercise that helps tighten muscles responsible for ejaculatory control. Become familiar with them by cutting off the flow of urine and then starting and stopping it repeatedly. Once you have the exercise down, practice your Kegels anywhere: at your desk, behind the wheel. Tighten your muscles and hold for a count of 10, then release.

3. Let Her Climb On

When she’s on top, your penis is less stimulated. And ask her to go slowly—long and fast thrusting is hazardous to a man’s endurance.
