You are hilarious. I like this.
Going off what you wrote, I began the topic because I myself have actually “married the best friend” too. Luckily I did it at an early age and ran fast. Abusive childhoods might have a lot to do with it, we have that much in common at least.
I could have so much fun with this, but I’m not an asshole. …Or am I? No. I’m not. Not today!
Damn, Shags moves fast!! 
It’s the vagina-scented underarms, yo.
Ha! You’ve been lurking well.
In my experience, the sexy knows it’s sexy and has options when the going gets tough. As such, they tend not to learn how to be a good partner and are worse than useless when the going gets tough. I’ll take homely and loyal ANY day over a hot coward.
I’m so damn old, I’m pretty sure I pre-date the sexy. By years.
Well, not to burst your bubble, I’ve been told sexy was born Nov.6th.
Of course there may be more than 1 sexy day.

Why are we all going along with the OP’s assumption that stability isn’t sexy? If that’s what women are looking for in a partner, then it is by definition sexy.
The premise of the OP boils down to “you should be attracted to what you’re attracted to”.
Okay, so this didn’t go CLANG for anyone else? Most people during their 20s do exactly the opposite - they do date the sexy, at least the sexiest they can manage. There are vast societal tropes (movies, books, songs, reality tv shows) about people dating rotten but sexy people (abusive cheating jerks for the girls, hot but crazy/mean/unfaithful for the guys) when they could have loyal, faithful so-and-so down the hall/at the office/etc. It seems that on average the first 10-15 years or so of sexual activity is learning that sexual attraction alone makes a poor selection system for a life partner.
As far as female fantasies - they’re typically about financially stable men, but those men are always emotionally problematic (or some sort of were-creature); the character arc of the male lead is that he’s healed by the protagonist’s Magic Vagina and sex with her average Jane self is more satisfying than the gold-digging supermodels/actresses he was having threesomes with in his penthouse, allowing him to get over the trust/daddy/mommy/sibling/esteem issues that drove him to success but left him a wounded puppy inside.
So no, I don’t see a trend of young women choosing accountants and actuaries in their 20s and sighing about what could have been. Penny typically goes for Leonard after a long streak of sexy hunks who aren’t thinking of settling down.
When one of my brothers were newly ‘singled’ after a contentious divorce was dating around, he continually brought these blond bombshells to family outings. He was lamentlng to me after another nasty break up, as to "why can’t I find a decent girl?. I tried to tell him what to look for. I explained that a girl who may be a bit plainer, and not so flashy might be a better choice. All that glitters is not gold.He flopped around for another 2 years, dating bad girls and cheating, lying bitches. It was so obvious to everyone where he was going wrong, except to himself. Finally he accidently ran into an ex classmate, they dated for several months. Now they are married, it seems to be a perfect match. She not ugly, but lets just say she has unfortunate challenges. And is a bit overweight. But we love her like a sister. He is very happy with her.
It’s deep thought gibberish like in the OP that makes me glad to be a faux-sexual.
^^Girl, what is faux-sexual? I have been laughing ever since I read that.
I am trying to think it out logically, but it comes up, nada, zilch. Cannot come up with a scenario.
I need to know.
That just tickles me!
(Please excuse me if it’s a real gender thing, I am woefully un-schooled on these things)
It means my lovers are invisible. Imaginary friends with benefits if you will.
Anybody can be congenial if you don’t have to live with them 24/7.
This is gold. 
This OP brings to mind the stereotype of women having different standards for sex partners than they do for relationship partners. Like most stereotypes, I believe at least a grain of truth is buried somewhere within it.
She fakes her orgasms, prolly.
Wait… It’s not faux (fake) sex. You are really having sex with an imaginary friend. So it’s faux partners. You have mis-named the thing.
Have you ever tried having an internet relationship?
I imagine she’d be a hot commodity. Most people don’t want to be catfished…
Exactly.
