Edging

Edging is when you get close to your orgasm and carefully stay right at the "edge" of your orgasm without backing down or going over the edge.  It's a common practice for guys, but it also makes a woman's orgasm much more intense.

It's easier to stay on the edge if you're using a vibrator.  The Hitachi Magic Wand is my personal favorite.  Don't rush.  Get as close to your orgasm as possible and use the vibrator to stay there.  Try to stay there for a few minutes and then let yourself orgasm.  It takes a lot of self control but it's worth it!
