Remedy for vagina tightening requires no drug.
Sexual ChiKong Intercourse instructs women to periodically contract the low abdomen and vagina muscle to synchronize love thrusts for acceleration of sexual response. That is how my lady achieve multiple orgasms in a very short time, 1 or 2 minutes. Most of the time we spend is to prepare the penis for further expansion (I call it the Power-up) beyond the normal erection, 20% more in size, and the vagina for tenting expansion.
Because the vagina will be naturally expanded in the intercouse when a woman shifts her sexual gear to the highest one, her original vagina tightening before sexual excitement becomes nonsense and useless. The most importance in this regard is the interacting force between the vagina and the penis in the love thrusting. As long as the penis/vagina experience a lot of stimulating forces each other, there are no reason to pursue the "Vagina Tightening" during the "peaceful" time. This is one of the fundmental principle of my Sexual ChiKong Intercourse that produces a highly interaction force during intercourse. One of the tricks in my Sexual ChiKong Intercourse is the periodic contraction of the vagina muscle during intercourse. IF the woman does it 1000 times in a love session (one night) and makes love 2 or 3 times a week, her vagina will become very powerful and well toned in 2 or 3 months. In this situation, the man will feel her vagina as tight as the Virgin's. Aging won't loosen the vagina muscle if a couple practices the Sexual ChiKong Intercourse.
Men may complain about their women's vagina loose when their penis erection becomes weak. Women don't feel any weak penis inside the vagina, either, but women always take the blame. Naturally, you will think the vagina is too loose. In fact, it is the penis' problem. The penis erection is the main problem of the sexual pleasure. In particular, men who don't know how to power up their penises during intercourse, will blame their women for the loosened vagina as a result of childbearing and aging. My Sexual ChiKong Intercourse can help solve this problem too.
The Sexual ChiKong Intercourse also takes advantage of the piezoelectricity generated by the symphysis pubis bone to electrically charge the penis and the vagina at the same time. The penis will become extremely hard and the vagina will become very wet and itchy. At this moment, what the couple expects is multiple, sexual orgasms, rather than complaining the vagina tightening.
I hope this help!
