I will add more later but for now ==> There is a word compersion. A feeling of joy when a loved one invests in and takes pleasure from another romantic or sexual relationship. It can be thought of as the opposite of "jealousy." It is a positive emotional reaction to a loved one's other relationship. I practice compersion, the opposite of jealousy, I gain happiness when those I care about are happier. I am seeking women who need multiple partners before they are truly and completely satisfied.
