How about I become a cheater?
What would make you call yourself a cheater?
I'm going to cheat on a person, a man.
That is not a good thing to do at all. If you think you are going to cheat on someone, you shouldn't get involved in relationships. You are only going to hurt the person that has been honest and faithful to you.
I'm really into the thought of cheating on a man.
If this is how you feel about relationships, then you just shouldn't get into one. Imagine the kind of hurt that you're going to cause people when you do decide to cheat on them?
