maybe it's Jua-gen...
chinese word meaning "Catch Veins"
i try it a few times in Singapore.
it was done by a 50yr old woman..
she will rub the balls, stroke the thighs, pull your shaft downwards,
basically massage your genitals in a non-sexual way..
she told me to hold it in as long as possible, try not to ejaculate..
i cum in about 10mins... and it was a fucking orgasmic explosion...
the old lady said this Jua-gen technique is an ancient art, and helps men to strengthen their dicks, prolong erection, prevent dripping after urination...
the way to judge the condition of the dick, is to try the Jua-gen and see how long you can last..
i lasted 10mins... and so has a young & uncontrolled dick... according to her.
she said she had some customers who come to her every 2 weeks for her Jua-gen..
and can last 45mins each session...
