Anal Shower Head Nozzle - Black Contains one anal shower head which can be attached onto a standard 1.27 cm (1/2 inch) shower hose. The shower head is designed so that there is no danger that water pressure gets too high. Please ensure that the water temperature does not excide 40 degrees centigrade. We recommend that you use a suitable lubricant when inserting the shower head into the rectum. Pay attention! Do you use the intimate douche both anally and vaginally? Always clean both the inside and the outside very well with lukewarm water and a toy cleaner to minimize any (harmful) bacteria.
