Agree with your main thesis; however, want to point out: the SLF frequent posters think that way not because they are attractive but because they are unattractive and are not able to attract any decent-looking SD's providing significant amount of allowance consistently (therefore they have to juggle multiple unattractive SD's each paying little and become prostitutes).

For example, that specific quote about "if only I wanted free sex" was from an over-weight SB, and her original quote wasn't "can get any man I want" but "can go to a bar" . . . in other words, she needs alcohol to make men see her as attractive. Rumor has it that, at bar closing time, all the UG's and even men pretending to be women get taken home by drunk men.

Instead of thinking of Emily Ratajkowski, a much closer image of the frequent posters on SLF should be Oprah Winfrey (at her heaviest, not when she was young) and Mrs Doubtfire, minus the intellect of either.

The very attractive girls, like the 9.5+ girl that I have been with for more than 3 years, stop traffic when they walk by just because people can't help staring at them (it's actually a little embarrassing and annoying to her; the police had to be called when she was at a golf driving range and some stalker started taking photos of her with telephoto lens from his car and was reported to her and the golf course management by by-standers), don't drink alcohol at all and don't go to bars. She was on SA for all of 3 days before I met her and took her off the "market" within a week. Girls like that hardly ever post on SLF because they enjoy their dating relationship with their SD's / SBF's, and have a feminine personality that doesn't find the need to brag online (like us men do).
