All humans were created with the capacity to feel a wide range of desires and emotions. But we were also made with the ability to control such desires.
You may not be able to keep certain desires from arising,but you can control your reaction to them.
Really,to act upon every sexual urge would be as wrong and foolish as hitting someone each time you felt anger.
Just as there is a "time to love and a time to hate" there is also a time to act on sexual urges and a time to refrain from doing so.
Ultimately,you are in control of your desires!
