My first Bob was also a Sliver Bullet! Through the years it has become old and sometimes works for me and other times does not . That was the best toy I have ever known and I once tried to replace it with a plastic bullet and it just isn't the same. The silver one slid over my clit and lips so smoothly. I never needed lube or anything with that one. The plastic one, on the other hand, dries me out. I really wish there was some Viagra I could give to my first Bob so that he would work all the time for me. But I guess I am just not ready to give up on it yet. It still has some spark left it it!
