Hypnosis may work for premature ejaculation. I know someone who was able to treat his PE with hypnosis and some other techniques. It's important to work with a good therapist and to really believe in it. If one does not go into it believing that hypnosis will work, then it probably won't.
There is no doubt however that we can change our thinking and behavior patterns through hypnosis. We can even do this ourselves. There are countless sources with information on self-hypnosis out there. If nothing else, hypnosis can help us relax which by itself can do wonders for premature ejaculation. I think that this is a good option for men who are not seeing results with other premature ejaculation treatments.
