A rocker is a type of sex toy designed for women to simulate sexual intercourse without a partner. Rocker designs vary, but they typically feature a plastic or silicone dildo mounted onto a frame or base. The woman straddles her rocker, and then manipulates it to receive stimulation.
Kinkly explains Rocker
Some rockers feature a dildo mounted to a curved base resembling a rocking chair. Another common variety features the dildo attached to a large wooden frame, which swings backwards and forwards. Some rockers also feature vibrating sections strategically placed near erogenous zones to enhance the woman’s pleasure.
Rockers are designed to give a woman complete control of speed and depth of penetration, helping her build to orgasm, and achieve satisfaction on her own. A rocker is also versatile enough to work for anal penetration, as well as vaginal intercourse.
As with traditional dildos, the rocker dildo should be thoroughly cleaned after use.
