Fucking women in relationships is a double-edged sword. Sure, it can be fun to be the other guy. You learn a lot about female nature, the taboo is exciting, and they fuck you like they just discovered it.

The flip side is the man they're with. You don't know him. I mean, you know his name is Kevin and he works in accounting, but you don't really know him, despite what she’s told you. You don't know how he’ll react if he finds out.

Let me illustrate this point for you. Some years ago I worked at a bar at a marina on a large busy lake. Great vibes, boats, lots of women, and I highly recommend doing that if you can. I met an attractive fit blonde woman who was in her 40s or so. One of those typical bored housewives who had everything, including too much time on her hands. So here I am, attractive dude in his late 20s, and we exchange numbers. We mess around a few times—it is what it is.

One night I'm at a different bar with some friends and I see her. We chat, we flirt, we're laughing. But the guy a few seats away is not. He is very unhappy. So unhappy that he walks up to me, shoves me, and tells me to leave. We go back and forth because I don't know who he is or what authority he thinks he has to tell me to leave. Turns out he had none; he just didn't like the fact I was flirting with his wife. (Of course I didn't know this was her husband) So the conversation ran short, and suddenly I have a bottle of Jack Daniels smashed over my head.

We fight. I got my shots in, and he got his, including slicing my wrist open in two places with the broken bottle. Nice! A bar fight! How badass! You might think, until you realize that could have been my neck. I go to the ER, and move on. She’s texting me, etc., but I block her.

A few weeks later I hear she's left town and her husband is selling the house.

The point of this story: people are capable of serious violence, and there’s no thrill in banging a woman in a relationship that’s worth that risk. There's no woman that justifies putting yourself in real danger just to get laid. Especially when, throughout all of human history, it’s never been easier to get laid.

So be smart and be selective. You don’t need to smash every girl you meet.
