A male masturbator is a sex toy designed for men to use for self-pleasure. It typically includes a sleeve or tunnel-like structure that simulates the feeling of vaginal, oral, or anal sex. Some male masturbators also feature vibrating or suction functions for added stimulation. These toys are often used for solo play but can also be incorporated into couples' sexual activities. Male masturbators come in a variety of shapes, sizes, and materials, catering to different preferences and desires.
