The Royal Swirl vibrator is a long swirl with the head of a penis. It is slim and powerful, good for overall stimulation. This vibrator is 7″ long and uses 2 AA batteries (not included). This vibrator is part of the Sue Johanson Royal Collection. Each item in the line is made from silicone. Silicone is hypoallergenic and more sterile, because it has no pores that hold bacteria. This vibrator is waterproof. Sue Johanson is host of Oxygen network’s Talk Sex with Sue Johanson and The Sunday Night Sex Show. Callers feel comfortable asking this grandmotherly nurse questions ranging from, “The condom slipped off, what should we do?” to “Is it okay to use vegetables to masturbate?” She is the recipient of the Order of Canada, the country?s highest honor for lifetime achievement.
