Male sex toys range in sizes, uses and function. Male toys are designed predominately for male masturbation use, due to their sexual stimulatory functions surrounding the penis. However, many male sex toys are intended as a sexual enhancement for use during sex. These devices come as attachments that fit onto the penis either increasing its length, girth, shape or add a vibration function. Sometimes referred to as male vibrators these adult male toys provide a pleasurable sensation through the use of vibrations to massage the penis whilst mimicking a vagina.
