A butterfly vibrator is a type of vibrator that has a long, narrow shape. They are typically made from silicone and are often smooth, but some are ribbed for more stimulation. Butterfly vibrators are often used for clitoral stimulation and are often marketed as a “solo” toy. Butterfly vibrators are often used by women and couples, but are also popular with gay men. In addition to the “solo” toy market, butterfly vibrators are also popular for use during sex as a clitoral stimulator during penetration. It is also possible to use them to stimulate the anus or vagina.
