It doesn't matter if they were born that way or not, it is no excuse for continuing the behavior.
Most men I would argue are not born with the desire to be with only one woman for life, yet most stay true to their wives and thus follow God's commands. If I can stay true to my wife, they can resist the urge to dirty their peckers.
I was born with a vast attraction to women. However, God would not overlook fornication and adultery if I did not repent.
