When I first started my punting career, it was to have sex.
I could get physical contact at a strip bar, but I needed the release as well.
Over time, it's evolved to where I go for the experience.
I rarely go just to pump and dump my load.
I'm there for them to fulfill certain positions, or if they remind me of someone, to fulfill that kind of fantasy.
When meeting with an established WG, it's always ok to share expectations.
Some are open to discussing it over phone/email/text.
Others prefer to discuss in person.
If the latter, always discuss expectations before exchanging your half of the bargain.
I'm always prepared to walk away if what I'm looking for isn't available or if they decide to upsell every request (kiss you, extra, kiss me, extra, touch my left boob, extra).
As for spreading your cheeks... if the WG also provides a prostrate massage, you might find something other than a tongue down there
Leaving a review is always helpful, regardless if the lady is still available or not.
If she comes back, then another punter would have their research already done.
