Good points Roth, and also the prossies chipping in with what every punter should be aware of anyway. I'm not keen on so much lube myself, partly as i like to feel when she is naturally wet enough (but might be inevitably necessary after she's had a long shift).
I also like Taggart's point, that it would be good to include fingering yes/no in reviews (not 'field reports' so much, which tend to be AW wank writing). Like OWO, it will probably be at the girl's discretion, but for many prossies, especially the quickie crew, it is a standard off-limits irrespective of the punter, his hands and his sensitivity. That a punter includes it in a review is no guarantee the next guy will get it but at least shows she doesn't refuse as a matter of principle.
