Prew sez: "Its easy for people to say 'wait' but when you do and you think he's the one, you find out he isn't who you thought at all ."

So when you find that out, I'm thinking, it would be easier to extricate yourself and move on to the next potential "one" if you weren't already sexually active/involved/committed with the wrong "one".

One of the characteristics of the "one" is that he won't pressure you to do something with him that you're not ready to do. If he tells you that it is (or that you are) "bad" when you want to first make sure that you're comfortable with the idea of sexual intimacy, he's a bad choice for the "one". Anyone who makes that kind of negative value judgment about you is somebody whose opinion is best ignored, and whose companionship is best avoided.
