You my friend need to get hip to the joys of
TANTRIC YOGA...
I personally practice a
Taoist sexual yoga that does the same thing basically.
The kundalini energy in your sacrum can be raised and cycled to refine it. The basic process is to draw it up the spine, into the brain, over the crown, down through the tongue touching the roof of the mouth, through the throat, along the front of the body and deposit it into the 2nd chakra (tan tien).
This is done through breathing, visualisation, intent, and a series of bandas (locks) that help create pressure to move the stuff around. Every cycle through this orbit (aka the Micro-Cosmic Orbit) refines the chi a little bit. As it is refined, its vibration is increased, and then it will naturally come to rest at a higher chakra.
Focus on individual chakras is not important. There are tons of chakras between the chakras, and people get lost in the map and forget the energy. If you do tantric work long enough, the need for visualisation stops and you can simply feel the energy and move it around at will.
Perhaps the most important banda to master is the squeezing of the perenium (that area between the balls and the anus known as the
taint). This muscle group needs to become very strong to connect the downward channel to the upward one... effectively connecting the nuts with the tailbone. Holding this lock while having an orgasm can block off the seminal tube and prevent ejaculation. Done with proper energy movement, the orgasm becomes entirely energetic, and the seminal vesicle doesn't even release semen. If you get really good, you can have multiple orgasms. (women ain't the only lucky ones)
You probably need to get yourself a good chi kung master. In lieu of that, read as many books as possible.
This old gem is still worth reading, and as it was one of my first tomes on the subject (back in the old days of the new age
aka the early 80's) I can heartily recommend it. Whatever you think of Mr. Mantak Chia, this stuff actually works. His Deer excercise differs from mine, but not by much... and certainly not enough to cause it not to work.
There are a ton of benefits to transmuting sexual energy. Too many to discuss here. It is not something you will master right out of the box. Like most worthy endeavors, practice makes perfect. At least with this practices you get to stroke your pocket snake while doing it.
Hehehehe.
Good luck on your journey.
