When you think realistic in sex toys you think as close looking to the natural human part as possible, right? Some people enjoy the aesthetic realism that sex toys feature. Realistic vibrators usually feature a strong penis-head very similar to the real thing. Some vibrators also feature a foreskin that actually moves just like a real foreskin. Realistic vibrators will also usually feature strong veins along the vibrator shaft. Another feature feature, although not usually for any specific purpose other than looking real is the scrotum on the vibrator.
