If you are having sex (to include masturbation) and reach orgasm with no intentions YOU ARE WASTING THAT ENERGY.
I'm not talking sex magic, but I'm talking sex magic.
The most obvious intention (and most instinctual) is procreation.
You can create anything, but the intention must be there and the PLAN must be there.
Just my two cents on a topic that is not really discussed.
Peace! And don't get herpes!
