A firm silicone plug designed especially for men, Tantus' Prostate Health Black is an anal adult toy with a special shape and tilted head to effectively reach and stimulate the prostate. A special waterproof mini-bullet vibrator also slides into the base to add extra thrills. A flat bottom is ideal for hands-free use, four raised ridges near the end of the shaft add extra textural pleasure, and an elongated base ensures safe use. A matte surface feels velvety, and firm, semi-flexible silicone is easy to insert and can be boiled to sterilize. Only water-based lubricants should be used with this toy.
