A butterfly vibrator is a sex toy designed specifically for the stimulation of the clitoris. This vibrator was invented by Joani Blank, an author and sex enthusiast. The toy, as its name suggests, resembles a butterfly; its body stimulates the clitoris, while the wings of the butterfly stimulate the labia and other surrounding areas. To keep it in place during intercourse or masturbation, the butterfly vibrator is outfitted with straps that wrap around the wearer's waist and thighs.
Butterfly vibrators were once quite popular but have since been replaced by couples' vibrators, which provide stimulation to both partners during penis in vagina sex and are more comfortable to wear.
