I got one. I used it two times so far. I noticed more sensation. I also started ejaculated easier. I think it lined up some of my nerves in just two uses. I have not tried it a third time because I don’t want to end up with premature ejaculation again. So I am taking it slow. It may not help anyone else. But I at least wanted it to be known. Most people know about viagra, and others, but not this.
