The scrotal tug is a technique for guys to postpone orgasm. If you often come quickly you can try the scrotal tug and see if it works. You can first try it during masturbation. If it helps you can use it during lovemaking.
When you come close to orgasm your testicles pull up close to your body.
Before you reach the point of no return you draw your testicles away from your body to delay ejaculation.
Circle the top of your scrotum with your thumb and index finger and pull your testicles down. This can also be done by your lover.
