Hello again.
I have read the text taoist81 talk about in google books in pag 51.
"Misterpreting the ping-i (an alternate name fo the hui-yin at the perineum) as "one inch
above the right nipple",he was mistakenly lead to claim disovery of a new
eyaculation control technique."
I think willes is who has a mistake .Here is the explanation:
1)I have just remembered ,i also read it in other book, called "Puntos de placer of su-nu hsuan tsai "
(http://www.lsf.com.ar/libros/71/PUNTOS-DEL-PLACER/ ) about reflexology of pleasure and it talk about 2 diferent points,one is the "millon point" and other diferent is the ping-i (with other name,it uses numbers not names,and it is the point 42 ).
excuse me but i only found spanish version,it also discusses about this point and this uses.
"It is an special point used only in man.It is a tsun on right nipple.
It is an autotratament point.
We press it constantly in vertical ,strong ,with index and middle fingers of left hand.
It will do while dual practique (intercouse, or penis stimulation)"
It said only press on male,never on woman;and it is used for seminal retention.
2)Also ,i would finish telling i have tried this technique several times,and it workes fine for me.
