I have heard about women who have enough control of their vaginal wall muscles that they can shoot ping-pong balls out. I have heard about a Korean/Chinese/Japanese adult show where a gal can insert a peeled banana and asks a guy how many pieces he wants it broken into and proceeds to do it while it is inside. Is this really possible? I can barely feel my wife's muscles contract when she reaches orgasm but she does not have good muscle control anywhere on her body. One guy posted something his girlfriend does on a dick that she can give the equivalent of a hand job with her vulva. I would guess that pelvic floor exercises (Kegels) may help out on this front. Are these shows/rumors true? How do I get my wife interested in doing these, for both my pleasure and hers?
These stories are true for the most part. In Amsterdam, I watched a sex show where a woman performer smoked a cigar with her vagina. Yes, the ping pong balls and fancy fucking are true of women who have developed their vaginal muscles. As for getting your wife to do anything related to sex, lots of luck. If I had the answer to that one, I most likely would have retired to a sun drenched Island and painted my life away. You could buy my vaginal Barbell as a gift that describes how to practice doing the exercise, but she might take is as a criticism and pout for days, months, etc.and you will never get any knookie again.
If you decide to communicate, begin the conversation with a compliment about how much you love this or that about her in bed. Then have the same conversation with her that we just had. Treat is as a curiosity not a demand. If it doesn't work, you can fantasize about a woman "milking your dick" until you shoot while masturbating.
