So there are a bunch of tricks to this, but the biggest problem is subtlety. In my experience, a good gentle way to prolong love-making is the gentle tug on the scrotum. Yep, the best way may be to bug him in the sac.
Yet you never really want to bug your lover while having sex. The trick is to play with his balls, often. That way if you reach down and give a gentle tug downward after some massage, he’ll think nothing of it. After some massage is the key to making it appear just another motion in your mutual lotion making. That combined with lots of ball play not aimed at slowing him down works wonders. He’ll just think you have a fetish for his nuts, which won’t bother him one bit.
