Million Dollar Vibrations
When you know where his 'million-dollar-spot' is, it will positively make sex sizzle for him.

This spot is located between his legs at about the centre of his perineum.

His perineum is the band of skin that runs from the base of his testicles to his anus. Men vary in sensitivity at different points on this erogenous zone so find the exact spot—the million-dollar-spot—that gives him the most pleasure. That million-dollar-spot is located over his prostate; when you stimulate this area it puts pressure on his prostate.

Stroke this area with your fingertips and ask him which part feels the best. Then take a vibrator and using it on low-speed, gently circle his million-dollar-spot. Always remember to use a lubricant with a vibrator to make it sexier.

Many men love this trick once they've been introduced to it although some may be a little bit inhibited at first the idea of you using a vibrator in this area.

How He Can Last Longer
Men are obsessed about lasting long enough during penetrative sex; if they're really turned on they start to worry they will climax before you're ready. You can use this trick very subtly so he won't feel that pressure.

Tell him how good it feels to pulsate his PC muscle—those are the pelvic floor muscles that run from his pubic bone around to his anus. (You also have pelvic floor muscles!)

When he's nice and erect during foreplay suggest that he pulsates his PC muscles.

Tell him that you've been told it strengthens the erection leading to a better orgasm once it's time to climax.  It does do this, too, but crucially he can learn to last longer.

When you actually get down to full sex ask him to do the pulsations again, and not only will you feel them inside you but they'll slow him down from reaching orgasm.

Here's how men can do kegel exercises (so important for his sexual fulfillment!) from Destin Gerek of EroticRockstar.com
