The point RIO makes is that there are too many men who make a choice to take advantage of and even search out the opportunities. Not all men and not the majority, IMO, but too many.
And to further that point, when you have an A with a MM, you've self-selected into exactly that group. The men who would do it are the only men available (outside of single men) to have affairs with. You won't be sought out for an A with a MM by a man who's not searching for A opportunities, it's a bit of a totality.
question - do you ever call other men out on this?
if it affects you and is a distinct lack of morality that puts others in jeopardy, shouldn't all men try to put a stop to it?
I do not call out other men on it. I avoid it now (after my W's A) and before I didn't engage in it, but also didn't see "the harm" in it either. I know that sounds terrible, but I had no idea the harm these men were doing to other men, the women (who often wound up divorced if there was a d-day) and everyone around them. It seemed like "boys will be boys" fun, and, for the women, it seemed to play into the "women like sex just as much as men" narrative that I'd grown up with (especially if they were single women or professionals). If everyone likes sex as much as I do, what's the harm in seducing and sleeping with a new woman? She'll enjoy it the same as I will and the world is a happier place for both of us, right? And that applies for single men too out there "playing the field".
I sure hope most guys aren't that way.
Let's say most guys aren't, just for the sake of discussion (in my personal life, it seems like most guys are, but, it matters not for this). Almost all guys seeking an A are. See my previous point, having an A is self-selecting into the group of guys who are, indeed, exactly like this. And there's either a shocking cognitive dissidence going on here or a misstating of what is actually attractive in men (or perhaps both), but, any women having an affair is putting her marriage, her health, her children and sometimes her job on the line to be with a man who is exactly the person that you (and every other woman I know) "hope not all guys are like". There's something there that doesn't make sense, I struggle to figure out how to dissect it further, but it's just hard to understand how "I hate men who sleep around" and "I will blow my marriage apart to be with a man who I know is sleeping around" can be true at the same time. For me (and a lot of men I know), I didn't hate women who slept around. In fact, I really liked them because I felt like I could lie less about my intentions. No, I wouldn't marry a woman like that but that wasn't my goal, so my desires (sex) and the women I pursed (those who slept around) were aligned. In an A; if sex isn't the goal (find someone to love and respect me) and the actions (have an A with a MM) are totally out of alignment.
It's also a choice to not play with fire. Don't allow or put yourself in a situation where you are in a private setting with a member of the opposite sex. Don't play with fire, test the waters or push the envelop. Married men and even single men do that. They make the choice to not test their resolve.
That's my tactic. Why risk it? If I find a woman sexually attractive I'll distance myself from her because of the danger to my marriage. People make fun of me for this, even here, and say I'm too hard line on it. Well, guess what, if every one of our WS's had done the same, unless it was just a totally out of the blue come on (which is very rare), they could shut SI down and we could all go home, because very few/none of their affairs ever would have happened. I have a very low chance of getting into a car accident every time I drive. I still wear my seatbelt every time I'm in the car. It's just common sense, the upside (being able to bounce around in the car isn't worth the downside (going through the windshield and being scraped up off the pavement). Women are nice, I like to be around women and enjoy their company. But a woman who's "hot" to me? No, that's taking off the seatbelt to see what happens. And taking it further, having dinner/drinks with that woman? That's driving drunk at 100MPH to see if I can do it. It's just crazy reckless, IMHO. I hold this as a truth, if most people do it long enough, they will eventually fail. Maybe not this week, next month or even next year. But eventually, they will.
