I have met few of Instagram SBs (more like a checkbox)...most of them are pro SB and travel around (usually Dubai or sometimes Paris or US). They don't care much about looks or age as long as you are rich. You just need to create a decent profile and show that you can afford. Most of them accept around 500-700...if you play your cards right but in personal experience its not worth it. Getting them is not difficult but the experience is not good. There are too proud with attitude. You can get an expensive escort and can have better fun because she will deliver good service. or meet a normal non professional next door type girl and for this much money she can show you heaven
.
Most I have payed to a SB is 500...and she is the most beautiful girl I have ever met...but there was nothing else other than looks.
SA is all about finding someone who is normal, has a life and work, and meet you not only for money but also because she enjoys your company with some added benefits. More life girlfriend without commitment. Takes time...but worth the effort.
So I haven't made out on my profile that I'm a millionaire. Maybe that would transform my success rate, but I've never seen the point given I'm not looking to pay 500-700. And offering 200 will only look silly if I'm supposed to be worth 6 million.
So I can only speak to my experience, which is that a lot of the Instagram girls are picky and won't necessarily even reply to messages (You say they don't care about age but I think the example above has said on their profile nobody over 50). Appreciate others' experience may be different. However, if you are rich and/or pay high allowances, relatively young and good looking then it's also worth considering that your experience may be above average. I may post a "fittest girls I've spotted" shortlist and see who here has banged them 😂 if it's as easy as you

say...
I agree with you that it's boring/pointless paying for a mechanical or soulless shag - whether SA or AW or otherwise. If I am honest, and maybe this sounds bad, but I think as long as I pay for sex, I'll always favour variety. I would always rather bang a new girl, than someone I've already banged. So I am not really on SA for a gf; and the "connection" side of it is possibly more limited for me as a result (assuming this takes multiple/long term meets to build). I look for good banter and easy flowing conversation, but beyond that, I've never met anyone who I thought was "dating" me for me, with the money a mere convenient bonus. And I'm ok with it being a little transactional (or at least, I accept I can't get away from that), so long as it's fun. But again, recognise others are different, have had freebies etc. Only speaking to my experience.
