Before meeting its best to have given her a quick phone call, or get her to ring you. Be upfront about what you want...does not need to be graphic, can be something like "Girl friend experience, plenty of kissing, and want oral without" for example. Usually get a feel pretty quickly whether okay or not. If you feel like backing out at this stage, do so. Must admit...being a lazy git...sometimes when booking through adult work sometimes cover this via e-mails...okay but not as reliable as phoning.
Onto meeting. Much simpler if its an outcall, of course. Then...if she's used false photos, or photos that are decades out of date..you just make excuse "left wallet in car", go and never re-appear.
Assuming photo test is passed, I offer money pretty quickly. (More organised geezers check agreed services first.) Then move in quickly for a quick grapple, start shedding clothes quickly, and removing some of hers. (Do not waste time in chit chat...a couple of minutes can grow to 5...to 10...etc.). I like a chat at some point of a long punt (shock, horror)...but bad move to do it at start. Wait until you are recovering from round 1.
In calls at your place or your hotel? Well personally never had an in call at "my place", never been an option, but it strikes me as a bad idea even if you're single. But even at a hotel...I think your options are limited. Think you have to be very careful in "pre-vetting" stage...look for reviews here, or meet them before at a parlour or their pad...because once they turn up, you need very fancy footwork to get out of appointment without paying. (Just too much potential for aggro...scenes with hotel, etc.)
