I've had some of the most pleasurable orgasms ever thanks to this thing. I have the oral orifice A and B size. I find A too stiff and tight and not pleasing at all. B on the other hand is perfect for my size. My preference is to have it on the lowest speed setting and just relax and let it do it's thing. Clean up is simple, just use some warm water and soap, dry it, then pat it down with baby powder.
