No prob.
Our minds are not controlled by our bodies......it is our bodies that often respond to the thoughts and functions of our mind. God created man to have only one penis to use with one woman during a sexual liasion......He created woman to have only one vagina to allow one man inside during sex. If our bodies were not designed to be monogamous, they would be created as such by Him. He created Adam and Eve, not Adam, Eve, and Becky (or Adam, Steve, and Eve). Yes, men are sexually attracted to women, women sexually attracted to men....but that is the mind triggering our senses, stimulating our senses. We don't have to always act on what stimulates us, however.
That's just my opinion.
