[QUOTE=MeowLuvStoroar;2194342]As for the very nice looking women not wanting anything from you but still on sugar daddy sites LOL, either you found yourself a unicorn or someone who can play the game better and have more patience for the bigger reward and probably want to settle down to be taken care of for life with a "real" relationship with a gentleman they met on a sugardaddy site.[/QUOTE]I assume you're a female (seemingly an older one who aspires to be an SB) here to share your perspective, and there's no reason you shouldn't be able to, but remember your perspective is of limited use if your purpose is to try to convince anyone to think along the same lines, because you're only peering through a single pair of female eyes whereas the collective experience of the SD's here brings the perspective of experience with hundreds, or probably thousands of SBs, not just one.
I'm not saying that most of the girls on an SB site don't have a financial motive, most of them surely do. But as I've written before there probably aren't many females on the planet that don't prefer a wealthy man to a poor one. Some of them do have a genuine attraction to older men, some maybe wouldn't go near someone twice their age unless there's money on the table, and some of them are as you said just fundamentally gold diggers that have very ambitious long-term plans. Some of them are plain old backpage or CL girls that have delusions of grandeur and want to pass themselves off as a true SB.
They are all out for something. Not necessarily cash payment though. All women are out for something, even in the civy dating world.
As far is how is it fair for an SD that's married to have an exclusive SB, well it becomes fair the moment the SB decides its the right arrangement for her and she signs up for it. If she feels it's not fair, its up to her to make that decision BEFORE agreeing to exclusivity. Fairness is defined by doing what you said you would do and sticking to your agreement. It has nothing to do with the terms of the agreement itself.
