A head teaser is a hands-free sex toy which sits on the end of the erect penis and, as its name suggests, stimulates its glans penis, commonly known as the head. Head teasers have a central cap made from a soft material such as thermoplastic rubber. Some head teasers are attached to bullet vibrators, which transmit vibrations to the penis, while others are attachments which can be affixed to compatible wand vibrators. Head teasers may have textured interiors to increase the user's pleasure.
Head teaser is sometimes spelled head teazer by some sex toy manufacturers.
