EVERYONE SAYS THAT MASTURBATING EARLY IN THE DAY HELPS SEX LAST LONGER THAT NIGHT. SOUNDS TOO EASY. DOES IT WORK?

Potentially, yes. It depends in part on your natural refractory period. If you can go multiple times in a row, then morning masturbation may have little effect. If you have a more moderate refractory period, then you may find that morning masturbation sets up your nighttime sex for a great start. During masturbation, visualize lasting longer during intercourse. It’s also a great time to practice the stop-start technique — bringing yourself to the verge of orgasm and then stopping and waiting for it to subside. This is one of the most reliable ways of learning to control the timing of your ejaculation.

MY GIRLFRIEND’S MOST-INTENSE ORGASMS HAPPEN WHEN HER FEET ARE UP IN THE AIR. WHY?

During sexual excitement, blood flows more intensely to the genitals. Putting her legs up may increase this rush of blood, making arousal and orgasm more intense. Take advantage of this: Have her rest her ankles on your shoulders in the missionary position, then move forward to rock against her clitoris with the base of your penis.

MY WIFE LOVES QUICKIES, BUT SHE RARELY HAS AN ORGASM DURING THESE ROMPS. HOW CAN I WARM UP HER ENGINES ON THE FLY?

Good news: She is probably ultrasatisfied already. Although quickies are rarely orgasmic for women, they can be both thrilling and fulfilling. Spontaneous or feverish sex is hot–plain and simple. That said, if you’re determined to boost her orgasm potential, let her take the lead to go after her own orgasm, or suggest her favorite, tried-and-true position. She might also consider masturbating or fantasizing preromp, or using a vibrator on her clitoris during sex. If she still doesn’t have an orgasm, remember to return the favor later with an all-about-her pleasure session.
