Getting an erection when you see any sexy girl means you are a cheat.
When your manhood rises for just any girl then you are a cheat in the making.
Your manhood suppose to choose who it rises up for.
Armed robbers once told a man to sleep with a lady member of the gang before his wife.
The manhood did not stand. It happened to another man and it stood.
I know you might say tension stopped it from working. But do you know it happened to someone else, and it was erected?
This is how to know a born cheat.
