But you can have an orgasm without ejaculation because that those things are separated from each other.
There are some interesting teaches about that I found, for example a book from Mantak Chia and other TAO related stuff.
With A.F. ejaculation is too heavy on you'r adrenals. I didn't know either until a couple of weeks ago. You'r body does everything to create new semen and kick you'r adrenals in the butt. I costs you 30 to 35% of you'r total energy if you've ejaculated. With A.F. you may have maybe 30/40 or 50% of you'r normal energy (not the baddest stage).. if you calculate a bit you understand that it is very stressing for A.F.
I've managed to get the same result, but without ejaculation by using a technique to draw the energy and attention away to other parts of the body.. but it is difficult, and I also have to use some 'locking' method to block the flow and silence the muscle contractions.. but it works.. but after a couple of months practice I think I can choose with my mind.
I'am used to meditate and do some yoga like practices for A.F. (sometimes to stop de palpitations, or relief some tightness) so I learned this very quick I think...
