Childbearing won't affect the women's ability to achieve sexual orgasm. As long as he can give you a 5-10 minute pressure massage on the pubis bone, your sex organ will get charged instantly, ready for penetration; as long as he frequently press his pubis bone his penis will be powered up. Compressing pubis bone will activate parasympathetical nerve to engorge your sex organ and erect his penis. From our experiences, childbearing and aging will relocate the uterus due to the loosening of the vagina muscle. So, we have invented the Sexual ChiKong Intercourse to tone the vagina muscle and prolong intercourse. It turns out that my lady always achieve eruptively multiple orgasms in 1 minutes after an itchy spot in her vagina/clitoris is developed and locked by the penis or pubic bone. The most important aspect of this method is that I feel energized everytime after intercourse and I can still hold an erection for 10 minutes after ejaculation. Where is the extra sexual energy coming from? The bioelectricity generated by the love trusting on the pubis bone charges my system during intercourse. As we usually have sex in the daytime/morning in the weeken, I don't have to take a nap after sex, because I feel my body get fully charged through intercourse.
Before you use my Sexual ChiKong Intercourse to tone your sexual muscle, you may have to adjust the attack angle between the penis and vagina to obtain a proper stimulation on the G-spot and Epicenter. The attached pictures in the file Attack.gif tell you what the attack angle means.
To give you the concept of Sexual ChiKong Intercourse, I attach 2 pictures in the file Sequence.gif to show you what I am talking about. Examine the sexual response on their faces very carefully in these pictures. You will understand how powerful the bioelectric surge is in their bodies when the lady achieves multiple, sexual orgasms..
