When love is true you can kiss.
When love is false, or not compatible, you cannot kiss the other person over and over again and feel what you should be feeling when kissing a true love.
Some of us already know this from our earliest kissing experiences. Yet, then again, in the business of life we may have forgotten this simple truth of nature, of the instincts, and of the soul.
Instincts are our genitals in interaction. Sexual desire and expression are our bodies and instincts at work to generate desire for the other person, and as in the old days, pregnancy and children.
Love compatibility between the sexes is not built by sexual desire, love-making techniques and free sexual expression.
