The beads range in size from a very tiny 3/8" to 1" allowing you to work your way comfortably to the larger beads. The entire string is 12 1/2" to the cock ring, so you can be either mild or mild when you use them. The cock ring begins at 1 3/8" in diameter, but the stretchy silicone allows a tight, comfortable fit for all sizes. Let the cock ring keep your erection rock hard and then amp up the sensations by inserting the beads! The tiny beginning bead size makes this a great set of beads for the beginner. Made of superior silicone these ten beads are hypo-allergenic, comfortably pliable and slightly stretchy. Made for the ultimate in comfort for anal play. The cock ring can double as a retrieval loop for safe and easy removal. Once lubricated gently insert the smallest set of beads, slowly insert the beads for as long as you feel comfortable. As you become more accustomed to the sensation you can start inserting the larger beads but it is best not to push too hard too fast. While you're climaxing, try pulling on the retrieval cord. As the beads begin to slide it creates incredible fun sensations! Don't forget to select a quality lubricant from my lubes and lotions page.
