Rayelan,
You are giving away all the secrets. This is supposed to only be known to lecherous guys like me. You are absolutely right however. The energy fields do merge (ying and Yang) and balance each other out. The ladies are not supposed to know what is happening to them however.
It took me quite some time to figure out why the hair on the back of my neck stood up when I was introduced to an attractive lady.
Unfortunately many people in the west confuse sexual attraction with pure love. This phenomena is much more widely known in the east. Unfortunately this knowledge is what leads to the abduction of young girls and they are used for energy extraction which totally devastes them. Some very corrupt oriental and others are actually stealing energy in an attempt to enliven their chakras and reach enlightenment, for man cannot become enlightened without woman.
Unfortunately, if you watch the oriental movies you will see the gansters actually eating sushi which has been laying on the bodies of the poor women soaking up their energy.
