Why Aries is unfaithful?

This is the sign of conquest and physical strength.
The Aries is not unfaithful to another, but always very true to himself. He is innocent and does not think of the damage he can cause. Like a child, he is only interested in getting what he wants and winning at all costs.
Competition and the challenge stimulate him and he will not be defeated by obstacles and negatives.
When he is unfaithful he does not hide it and it is very easy to find out, as to a kid who has made a prank.
Tip: Always flatter him and provide some resistance.
