This pump is the best invention ever created better than the wheel. I have noticed 100 percent clitoris growth from 2 inches to 4 inches. I can even use my clitoris for anal sex with my husband. I have the creamiest orgasms ever. One big downfall is that sometimes I passout from the massive amounts of blood that flow to my clitoris. But all of the injuries I have obtained from passing are worth every bone tinging orgasm
