The terms stroker and masturbator are often used interchangeably, but there are slight differences. Strokers are typically smaller, handheld sleeves that require manual movement, offering a more controlled, hands-on experience. They may be open-ended or closed for suction effects. Masturbators, on the other hand, often refer to larger, high-tech devices that may feature automatic thrusting, vibration, suction, or interactive elements, reducing the need for manual effort. While strokers provide a simple, affordable option, masturbators deliver a more intense, immersive experience, sometimes even syncing with adult content for virtual stimulation.
