My Milkshake Brings All The Boys To The Yard
In the early days I met a few escorts who would try and wind the time down by doing a lot of holding and hugging. There is an American term for a client who gets this treatment but I can't remember it. These escorts had quite a lot of good reviews so could not always have been asleep on the job. I avoided them after that. See for me is not the be all and end all, but without it, it doesn't fly either.
To me companionship is important also and someone who appears to appreciate you as a client and with whom you can discuss things. That said, I have occasionally heard mention of a client who might just come for companionship, one mentioned having a client who only dances with her for instance, but I would guess these are a smallish minority.
