I voted yes, because I think that many people here aren't voting honestly. In an ideal situation where there was ABSOLUTELY no chance of getting caught sleeping with the ideal woman, I think that many people here would but their morals aside for the moment and do it. Remember, many guys are easily distracted by beautiful women, and use their "other" head to make their relationship decisions.
Of course, there is no such thing as the perfect crime, which makes the whole vote somewhat meaningless. We KNOW that we would all get caught eventually, and that would stop most people from trying it.
