Penis enlargement
A few different research studies have demonstrated the utility of hypnosis in enlarging beasts. My attitude is that what is good for the goose is good for the gander. I have not heard any research dome on this issue yet. It makes pefectl sense that hypnosis would produce better erection. Whether it would produce actual enlargement I personally doubt.
However, most probably a better longer lasting erection is very useful to some people. I do not have an audio on this yet but it is on the list of things to do.
If you are interested in such an audio send me an email to suggest future audios.
