I love this sucker and I got it yesterday. I've already tried weak bullet vibes and this sucker really packs a punch. I seriously think a 9 volt battery version of this should be made, better yet even an option for 2 9Vs! Yes a guy can use this too :-) Simply secure this thing to your cock using either a condom or an elastic band that's not too tight. Wowa!! For me, the higher the intensity the better.
