I'm finding it fairly tricky with some high profile providers. Caio was the exception - extremely organized, extremely professional. For many with substantial OF followings, however, I suspect escorting is an insignificant part of their revenue stream (I'm sure that's true for Caio) and for some that means that they don't take it seriously. I lucked out on catching Roxas Caelum on a 24hr visit to Toronto (client paid?). Nice guy, nice experience. I had no problems arranging an appointment with Ray Diesel when he visited London (nice but talks too much). I had a fairly long, pleasant WhatsApp chat with Luccas Toblerone which unfortunately ended with an appointment that he flaked on. Same with Kau Cobra. I tried to arrange an appointment for a month ahead with FullMetalTwunk when he was visiting Paris - all I got was a "Sure" and his rate, he ghosted me after that as I tried to set up a date and time. Oh well. It's hit and miss.
