What's up Doc? I wrote you before in regards to anal sex. Now, I have just finished reading you website about to ChiKong and I wanted to know if the Chikong method should be pratice throughout intercourse or just before I think I'm going to ejaculate?

You should practice it every day 5-10 times. Step-by-step (stepwise) inhale with expanding your low abdomen until your lung is full. Hold your breath for 1-3 minutes, than release.
Apply this method to intercourse. If you are a new practicer, you may have to an expanded low abdomen to penetrate. Then synchronize your stepwise inhaling to love thrust until your lung is full. Hold your breath to thrust for 1-3 minutes. Then take a break or change love position.
If you are not over excited, you don't have to hold your expanded low expanded. When I was young, I held an expanded abdomen for penetration. After I have gotten used to making love, I have no long held an expanded andomen any time unless I want to eliminate ejaculation at the final moment. This practice can numb my penis after 30 minute continuos thrusts.
