Fact: The Main Trigger For Ejaculation

The main trigger point for ejaculation is the frenulum – the area under the head of the penis, which houses the most nerve endings, says Paul Nelson, a certified sexuality educator.

Use It: Swipe your tongue back and forth over the frenulum, says sexologist Jessica O’Reilly, author of The New Sex Bible. Alternate this motion with slowly, sensually sucking the penis head.

Fact: Ejaculation

When he ejaculates, he feels six to 10 strong PC muscle contractions and a pumping sensation in his prostate.

Use It: Press your fingers just behind his testicles, on his perineum, says O’Reilly. It’s a pleasure spot.

Use It: Help him get there: Rhythmically tense your pelvic-floor muscles to put pressure on the base of his shaft, says O’Reilly.
