Steve Bodansky wrote the book "Orgasm XXL". And in California there are several institutes that teach the 1 hour orgasm.
A few years ago I visited several experts there. I also got to know the more humble and slimmed-down version of OMing (Orgasmic Meditation), which only takes 15 minutes.
And all of this is about the woman and her experience. Do you think these XXL climaxes, which are said to last up to an hour or more, are possible?
