I’m not sure I’ve never heard that. An SP pointing out sex can’t last the whole hour. Wouldn’t come into the equation with me as I like foreplay, the kissing, oral etc. Just mildly curious (it’s a boring Saturday), do you guys think if you wanted to have an hour of penetration, that would be an obvious no no?
Mind you, if it was fucking all the way, I’d never last 
Yes, I'd expect 100% penetration for an hour to be a no no.
Bookings aren't 100% penetration. There's kissing, foreplay both ways, some penetration and maybe a blowjob and/or handjob. I don't think I was being unreasonable expecting provision of some kind of sexual service for say 50 minutes of the booking with the odd bit of chat thrown in. We had a difference of opinion on the matter so I left and she refunded me some of the money.
She also tried to charge me £10 more at the start and I had to show her her AW page with the hourly rate on and then she said "ok".
