While many butterfly vibrators have larger harnesses that make them only good for solo use, a number of newer models have been designed with less obtrusive harnesses and smaller units so that they can be worn during intercourse, adding clitoral vibrations to the excitement of penetration. For added excitement, try the remote-controlled panty. Your significant other will enjoy randomly turning you on and off during a movie, grocery shopping trip, bowling game, etc. The intensity of vibrators can range from very gentle and designed purely for relaxation, to a vibration that's overpowering and potentially uncomfortable. Always start using your vibrator on its lowest intensity setting, and then gradually experiment with higher settings until you determine what feels best for you.
Many women enjoy diffusing the vibrations by placing a towel or piece of cloth over their vibrators.
This trick has been raved about for years, and is especially effective with electric vibrators. Power Vibrators can plug into a wall socket or use batteries. Some people prefer battery-powered vibes they're less expensive and more portable. Other people swear by AC-powered vibrators, because of the stronger vibration and greater durability. The variable speed settings on most AC vibrators afford a little more control over what kind of sensation you experience, which is really nice if you like a fast, intense vibe interchanged with a slow, gentle pulse.
