Should any indication of reluctance to discuss/ confirm services on a profile serve as an automatic rule out through the course of qualification?
IMO, no. For me it's a warning (yellow) flag, and a risk factor to go into the mix with all the other considerations, e.g. credible reviews, a phone conversation to discuss a potential meet etc.. That said, all these do is tell you whether a meet is going to be high risk or not.
"Q. What do you do in the 1h service?
A. It is not about what I do in the 1h, as my services, if I should start mentioning it like a poem, are the normal ones. For me, at least, it is mostly about actually enjoying, having fun, taking your time."
Reading this fluff I conclude one of two things:
1) It's a red card she can play at any time to deny any service that are on her Enjoys list (i.e. they were never on offer), or
2) She's a space cadet and doesn't see this kind of work as a transaction for services rendered but more as an "experience". So you may get the things on the list or you may not depending on the mood/flow blah blah.
I'm actually leaning towards believing the list. Pussy pumping aside, it actually is pretty vanilla e.g. no anal/CIM which you see on many expansive lists where Sergei has ticked all the boxes. There are some fetish ones (BDSM, watersports, fisting etc) but they are all giving.
If she is more experiencial, then it might be truly awesome particularly since she does look hot. However, she's Romanian and the 1 review here (which has no real credibility to be fair) is negative. She would have to be mighty convincing on the phone for me to book and if there were a £50 quickie session, it might be worth the risk to explore.
