Apologies to Margaret, but I do get asked frequently what women can do to improve their orgasms. And while I can't make their partners spend more time on foreplay, I wholeheartedly endorse the Kegel for improved sex. Kegel exercises are basically a workout for your "pelvic floor" muscles. Just like your triceps and your abs, the muscles around the vagina--called the PC muscles--can be made stronger with exercise. Here's your how-to Kegel checklist.

• To isolate the right muscles, the next time you're emptying your bladder, stop the flow of urine. The muscles you contracted are the ones you want to exercise. You can also insert a finger inside your vagina and squeeze the surrounding muscles. You should be able to feel your vagina tighten and pull your finger inside.

• To do a Kegel, tighten the PC muscles as much as you can, hold for a count of three, then release all the way and relax for a count of three.

• Do a set of five if you can--it's harder than it sounds at first. But your PC muscles will respond faster than your abs do.

• Work up to a count of ten, resting for five to ten seconds in between, with ten reps per set, several times a day.

• You can do Kegels on the train, at red lights, during commercials...the possibilities are endless. And just like any workout, it takes time to see results.

• But don't practice these in the bathroom; too much interference with urination will weaken your bladder and may lead to retention of urine and bladder infections.

Strong PC muscles are great for sex--you may find that your orgasms are more intense and last longer. And you may even be able to get your guy off by just contracting your muscles around his penis--it's called the "mare's position" in the Kama Sutra. That would make sex pretty memorable. An extra benefit to doing Kegels is extra tone around your bladder--you'll thank yourself when you're older.  And they're not just for women--guys can benefit, too.  Have you tried to do Kegels?  Has it changed your sex life?
