Where is the Line?

My friend, Shannon, and I recently discussed  "The Line." You know, the line you do not cross if you are married, or the person on the other side of the line is married. As you may have guessed, Shannon is a woman. But she thinks a lot like me, her sense of humor is almost exactly like mine (for this reason I have made her an honorary "Bull"- she is the first "Cow".  Yes, I have the authority to add "Bulls.")  Here's the deal:  I amuse myself by acting like I would do things that I never would. When relating a story to my wife, I always try to add a "tough guy" comment. For example, I will say, "So the checkout lady asked if I had forgotten about the pop on the bottom of my cart, and I said, 'Yes, but I have not forgotten my fists! Pow!'" And that is how I feel when I talk about sex with women friends. I will only do it when I know that they know I'm full of shit, that I would never do anything to jeopardize my marriage. As I told Shannon:  "Words, by and large, cannot offend me. As I think back on it, the only thing my first wife said to another person that bothered me was 'I love you.' And then, too, she let him put his penis in her vagina, and who knows where else, and that is where I draw the line."
