Double penetration dildos are designed for simultaneous double penetration and double stimulation. Double ended dildos come equipped with two heads instead of just one. A double dildo can be used by men or women, vaginally or anally. If you're using a double dildo as a couple, one person can be penetrated while the other controls the depth with the other end, or you can do dual penetration together (this may take a few tries and definitely a good sense of humor). Double dildos can also be used for solo play where the other end is used as a handle. Used together or alone, double penetration dildos are a great sex toy to enhance your sex life and relationship.
