"No" is a simple concept. If a girl says "no" or "stop" or "I don't want to do that," then a guy stops.

Not quite as simple as it sounds.

From the article:
"When she said stop, she started laughing and tickling me, and we started fooling around again," he said.

If this guy's story is to be believed: She says stop. He does. Then she initiates the additional fooling around. If the "stop" was real in the first place, was it cancelled by her reinitiating the fooling around? It certainly sounds like a case of mixed messages on her part.

Of course it was mixed messages. Don't you remember that sort of stuff? You fool around, then when you get to a certain stage, she says "stop." She doesn't mean stop completely, just stop going beyond a certain point. You continue to fool around, and she says "stop" again when you pass the comfort zone. Next date, that zone shifts. Eventually, it goes away altogether. The point is that when she says "stop," you stop. Women are human beings, too. They want to have sex, too. But...the risk is higher for them, right? So, it's a process. I'm 58 years old, but I remember my youth and that process. It's very simply. You fool around, with mutual pleasure in the process. If either party calls a halt, you back off. It's very simple. If you respect your partner, you respect your partner. If you don't, then you're a boor. I remember one time being told to stop after intercourse had already started. I stopped. What else would I do?
