The thing is, I see it as abuse, using another woman, and I could not see myself doing this.
I never did before, but I do now. This is exactly how I see it today. But, in the past, I saw it entirely differently; I used to have NSA regularly and I didn't see it as abusing anyone at all.
Let me explain a bit. When I was younger, I came at sex from the "feminist" perspective. Growing up, I was taught men and women enjoyed sex the same, and just as much and, for the time, a "sex positive" household. Now, I'm sure this was an unintended side effect, but I internalized that message and it guided by behavior dating and sleeping with women.
See, if "we enjoy it the same", what is the harm in talking a woman out of her panties for a ONS? Or, in this example, lying to a woman about my M status to have sex, then not calling again? I wouldn't be upset about that, I had sex, sex is something I enjoy, so, while I might be sad I won't have sex with that person again, it's not like I regret the sex I had with them. It's like traveling to another country and having a great meal, no, I'll never be back here again, but, yes, I'm glad I had the experience.
Thing is, it seems that whole line of thinking was flawed. I'll speak to my personal experience, but, when my W and I talk about our past sexual experiences, she has nothing but negative. She didn't enjoy sex with other people very much, she has a ton of shame for what she did, and, if she could, she'd take it all back. 100X for the sex from the affair, it makes her sick today and she'd do anything (her words) to make it go away.
For me, it's very different. I have mostly (almost all) positive experiences with sex. I look back on people I had sex with in the past with a smile, I enjoyed spending that time with them and enjoyed having sex with them. Yes, like everyone, I have a few regrettable sexual experiences, but, even racking my brain right now, I'm having trouble remembering more than 2 (both alcohol induced, good reason to quit drinking, right RIO!). I don't regret the sex I had with other people, if anything, I have fond memories of it.
So, back to the beginning, if we start from the basis of "men and women enjoy sex the same/equally" and, given how I personally enjoy sex, it follows that there's "no harm" in a ONS or NSA sex. Talking someone out of their panties makes us both happier (this is what I believed, misguided as it may have been), so, in effect, lying or misconstruing my long term intentions is doing both of us a favor because, if you believe it, we both get to have sex.
I want to note, I'm not advancing that last statement as a fact, I'm putting it out there to expose how I used to think and how I viewed sex as pretty much a "universal good" for both men and women. A night having sex with someone is better than a night alone, so, why not "kick some game" and try to get that girl into bed, right?
Well.. I was wrong. This site and others proved that to me without any shadow of doubt at all. I'm sure in my carousing days I talked a few married women into bed (I didn't know, didn't ask, and didn't care; no, this is also NOT right, but, it's who I was), and, if those women are anything like the WW's here, they deeply regret that decision. I made the world a much crappier place by what I was doing, yes, it made me happy, but, if I'd known what I was doing to other people it wouldn't have, not at all! Looking back on it, the entire thing makes me upset with myself and sad for the women. And, with my WW as the model, married or not, at least some women wind up regretting most of the sex they have. And the kind of sex I was having (ONS/NSA) seems to be the highest on the "wish I didn't do that" list for most.
Let's make this a little more personal. Before I met my W, I was NSA with a girl named Jane. We had a pretty electric sex life and it was obvious that she wanted to be "more", but I was dancing around and not committing. But, even a few years ago, a decade after I last say her, I'd think back and smile, "Wow, Jane and I had a great time together" (almost all of which was between the sheets). I smiled not out of a smug "I got mine", but because I thought we really both enjoyed that time together. I imagined Jane married with 2 kids thinking the same, "Man, I'm glad I met RIO, he was a fun guy". And I believed that right up until the A and the mountain of reading I did to the "why's". Now, I don't believe it at all. She probably thinks, much like my W does about her past partners, in short "I wish I'd never met him/had sex with him". My W had sex with about 10 people before we got together, she regrets every single one of them, why would Jane be any different?
It's a total mind f**k. And looping this all around to the topic at hand, I struggle to see how that same mind f**k wouldn't drastically impact my enjoyment or willingness to participate in a "free pass" type of sexual encounter. Is this person sleeping with me simply because they are like I am, horny and want a lay, or because they feel something emotional, want something more, are hoping for a connection/love/etc? How the heck could I ever figure that out? I know my W very well, I struggle every day with sex because of these very thoughts, "She had A sex to keep the kibbles coming, not because she wanted sex; how is this any different?". IDK. But I do know that it would be very, very hard to believe a woman in the "free pass" situation would really be OK with what that "relationship" would entail.
Closing it off, my grandfather always used to say "There's no free lunch". Well, a "free pass" is basically permission to use someone else as you would a prostitute but not pay. Seems like a free lunch to me, right! Well, no, see above, there's no free lunch. There's a reason you have to pay women to act like a prostitute (and do not have to pay men to do the same), because it's not something that fulfills or is desirable to most women. My grandfather was mostly right, but he missed an important point, there is a "free lunch", we all have it available to us. All you have to do it steal your coworkers sandwich, or dine and dash at your local eatery. Except that both of those actions, while, yes, they do lead to a "free lunch" are decidedly immoral and injure other people. I'm not paying for lunch, someone ELSE is. And that's how I've come to view NSA sex, someone is going to "pay" for this, either the woman via regret and disgust with herself for sleeping with me or me, via cash to a professional. I have plenty of cash, I'd rather pay than "steal" someone else's lunch.
The final thing I'll say, I'm well aware that there are really women out there who are offering a "real" free lunch. We see some women post about it here, where they have no reason to lie. It seems that some posters here have had good experiences with NSA/ONS type sex. The problem is, I have no idea how to identify these women. My W certainly appeared to be one of them during her A and in past relationships too. But she wasn't, she was offering a free lunch with the hopes that you'd give a really good tip after dining. And was deeply hurt, both in the A and in her pre-marriage relationships when guys came, ate the food, and then left without leaving a tip. But if lots of people put out the "free lunch" sign, but some (most of, IMHO) those people are doing that in hopes of getting a great tip for that lunch, how do you know when you see the sign if this lunch is actually free and given as an act of kindness or if it's a ploy to get a big tip? I have no idea. And that's a very fundamental problem I see with any NSA type relationship for a man, doubly so if he's married.
