The position you’re in while fucking can affect your ability to maintain arousal without ejaculating. Most experts agree that the typical ‘missionary’ position with the man on top of his partner is not the best to extend lovemaking.
When you’re on top, you have to support your weight. This generates muscle tension in your arms, shoulders, back, and legs. Along with the added excitement, thrusting motions increase this tension and cause more fatigue.
Like most guys, you’ll probably clench your pelvis, butt, stomach, and rosetta while pumping from above. All of this can reduce relaxation and increase your chance of slipping past against your will.

Who Takes The Upper Bunk?

Many men find it easier to prolong lovemaking with the woman on top, because there’s less muscle tension and greater relaxation. This position also reduces some men’s sensitivity. You’ll find the exercises in this chapter start with you underneath for these reasons. Try laying on your back with your partner on top, allowing her to control the old in and out. In this position, she can support her weight relatively effortlessly by kneeling. In addition to reducing tension and excitement, you can more easily guide your partner’s motions this way. Many women like being above because it gives them maximum freedom of movement, enhancing their pleasure without the feeling of confinement underneath. Not to mention that the “superior” woman arrangement frees both partners’ hands for sensual touching all over. I know some men have a problem with what they call the “inferior” position. If you’re one of them, getting used to being on the bottom will require an adjustment. If you need convincing to try it, just chalk it up to an essential step in your spiritual transformation. Tantra teaches that we’re each responsible for our own pleasure. Your primary concern should be on consciously surrendering to receiving pleasure, whatever the position is. If you haven’t dropped that old macho thing and accepted the fact that we’re all in this together to exchange ecstasy, then it’s time for you to start.
