I reccomend Michael Winn to westerners. He is a very down-to-earth, practical and gentle teacher, and very accessible. Mantak Chia's books can be found on the web, and they are very detailed in their instruction, but may be too dense reading for some.

Michael Winn sells dvds that are easy to follow. He has combined Chia's work with Chi gung. That goes well with Robert Bruce's AP work.

I recommend a practice by Mantak called the "Inner smile" meditation. Try to do that every day. As mentioned by others in here, the key to transforming the sexual energy is to open the heart chakra. Root chakra sexual energy, brought up into the heart, changes how you feel and use it.

Start with 6 healing sounds and inner smile. Jumping ahead to microcosmit orbit before you have done significant work to clear out blockages and open your heart energy could cause you troubles.

love and light and Chi!!
