This is my recommendation: (and if any other providers out there find this post and have something extra to contribute, I more than welcome your input in the comments) Bring double the agreed-upon donation to your appointment. Give her the base fee immediately. (I can’t stress this enough — don’t haggle or ask what you’re getting. You made the appointment, she got herself ready for you and maybe even paid for a hotel room, just give her the fee. Place it somewhere where she can see it and do not discuss it at all.) If she expects an extra donation for extra services, she’ll let you know as soon as she is comfortable doing so. Some escorts charge a lower base fee and require more money for sexy time, others (like me) charge a little more up front and include release in the session.
Some charge a very high fee and also charge for extras, while others (usually crackheads) charge next to nothing and couldn’t care less about a tip, they’re just trying to get you out the door with as little effort and time spent possible so they can get their rock. Stay away from those girls! Ha. What I’m saying is that all providers are different; what’s included in the session and what is extra depends completely upon the escort and what she is comfortable doing. I knew one girl who loved it up the ass so much she included it with her base fee, but then charged double for vaginal sex. You never know.
Whatever happens, if your provider gives you good quality service, she deserves to be rewarded. Make sure to give her at least a 40% gratuity, either by way of negotiating for extras or just handing it to her as you leave to let her know you appreciate her effort. This is how you get good referrals, fellas, not to mention good karma. This is a luxury service, after all.
