Guys who have (one-sided) Open LTR's: why?

Because I far outclassed the ho in social standing so my side was open, not hers....long term she eventually cheats or goes bolistic.

why can't you satisfy that need through seeing the occasional prostitute?

The amount of effort I've put into developing myself to be a "catch" or at the very least, an unregrettable one night stand means I don't have to pay with my hard earned cash.

Do you need the psychological validation of plates to feel good about yourself and maintain abundance mentality?

No, I enjoy the chase. The romance. It's the same reason I don't pay to hunt on a game farm. I enjoy the hunt itself more than the kill.

Ofc, TRP would criticize this not only because it's a shitty thing to do and that this validation seeking behavior is weak,

It's human nature to want to feel wanted. If you're making good money and want to bust a nut with no effort outside of your wallet, than lead with that. Most men can't. Including myself in relation to how much I like to bust a nut.

but especially because those shortcuts would eventually end in shitstorms of catastrophical propotions long-term and I had to find that out the hard way multiple times.

What shortcuts? Fucking girls you'd never date? I have plates a decade old. I'm a safe fuck when she's between men. She knows and I know it'll never be nothing more but it doesn't end in a shit storm because those boundaries are set in stone, by me.

being upfront about casual intentions never made much sense to me either, as them also sleeping with other guys and putting in the same minimal effort as myself would make it feel almost as transactional as going to a prostitute.

YMMV but experience is these women will try extra hard, even more the second, third and so on times they come crawling back when they couldn't secure the ring somewhere else.

Plating that way, at least to me, and especially if you already have a main girl, only makes sense if you have a very organical pipeline to replace churn and rather limited amounts of $.

Again, I enjoy the hunt. The authentic desire. I know when I'm fucking, it's because of who I am, not how deep my pocket is. Maybe that's a fragile ego, maybe it's the fact I know I'm worth more than my check book.

Hos give it away to shitty men all the time, for free...why would you pay to dick a skank down?

Great you are hyper independent, so you need nothing from a man apart from someone to hang out with. That sounds attractive to me. No hypergamous leeching. I would be interested. So what is the problem? Men who don't wash and exercise seem to be the complaints. Ok well I do wash and exercise as do most of my friends. There seem to be lots of men who do this, so what is the problem?

Ah yes, they are not trying hard enough to give you more than you already give yourself and you do pamper yourself don't you. I see what you really wanted was more. That's just good old hypergamy except almost no one can give you that without being a wealthy successful full time mega simp and lets face it, why would a wealthy successful man be a full time mega simp to an entitled self obsessed female?

Feminism has created women who are unlovable and incapable of wanting men.

But if you already have those skills and an attractive partner but just in need of a little sexual variety on the side, why can't you satisfy that need through seeing the occasional prostitute?

Why are you asking us? This is a question that only you can answer for yourself.

Do you need the psychological validation of plates to feel good about yourself and maintain abundance mentality?

Do you?

When I was actively plating, I got off on being as opaque as possible in regard to commitment towards girls because I loved how much investment that would reap me and found it very validating.

Ok, so you're validation farming. That's valid, and you're honest with yourself about it.

Ofc, TRP would criticize this not only because it's a shitty thing to do

It's not a shitty thing to do. Women do it to men ALL THE TIME. You are allowed to do it. No law against it, dating is amoral, and you are entitled to do this if you wish.

It's not for me, but I accept that it's for you.

and that this validation seeking behavior is weak,

Yeah, it's needy and doesn't get you what you think it gets you. Validation is a leading indicator, an instrumental goal. People (and you) like these things because it implies they can get other things (eg sex with more women) later. But leading indicators are only that: indicators.

but especially because those shortcuts would eventually end in shitstorms of catastrophical propotions long-term and I had to find that out the hard way multiple times.

Haha right. That's the downside, and that's why most men are fairly up front when they have the abundance to afford it. Losing 50% of girls early beats half of them going mental later.

OTOH, being upfront about casual intentions never made much sense to me either,

But you're not doing casual, you are doing friends with benefits. Repeated sexual encounters. Somewhat ongoing. Casual is basically one night stands. You're doing OLTR / FWB, and that's not "casual" and shouldn't be framed as such.

Call it a fling or an affair or an ongoing thing - women respond better to framing like this.

as them also sleeping with other guys

Some will, some won't.

and putting in the same minimal effort as myself would make it feel almost as transactional as going to a prostitute.

Except it's not.

Casual is: sex sex.

Prostitute is money sex.

Relationship is commitment sex.

Of these, the casual thing is the least transactional. Both sides get sex. It's only transactional if she has sex and tries to get something (eg commitment) later.

Minimal effort is basically non transactional.

You've got some work to do here dude, to understand that all human sexual relationships are transactional - everybody gets something and everybody gives something. Everyone is fine with this if they give what they want to give and get what they want to get.

When people say "transactional sex", they usually mean your resources for her sex. Either money or commitment.

Plating that way, at least to me, and especially if you already have a main girl, only makes sense if you have a very organical pipeline to replace churn and rather limited amounts of $.

See, this is where you've got some thinking to do. You sound like you're rationalising rather than making choices. And you're a little wonky in your thinking, you've got some definitions to tighten up in your head.

Fundamentally, the odd thing in your post is this: you like validation, but you're arguing for a zero validation arrangement.
