I have recently tried lots of masturbators. I lube them, put them under a pillow and screw them like crazy. Safe sex, little mess, and it cost less than wining and dining someone to get some action. Anyway, this is the best I've ever used. I put two of them together and wrap them in a towel. . . and then put them under a pillow. It is a love tunnel all the way. The ridges inside make all the difference. IT IS GREAT!!!!
