These realistic vibrators are designed to resemble the real penis. It's almost impossible to tell the difference. Some of these lifelike realistic vibrators are made with Cyberskin, an amazingly lifelike skin substitute that feels like a real penis. Most of lifelike vibrators are "fleshy" feeling and will have a penis-shaped head and veined texture to the shaft. Unlike a realistic dildo, many woman prefer the realistic vibrators for the sensation of fullness and the added bonus of internal stimulation.
