it's not standard and depends on a regular escort versus a first time meet. With a regular escort I would say 30 to 45 minutes of sex. No need to chat until after we've had out fun. With a first timer need to chat a bit because sometimes texting and working out what we both "enjoy" takes a bit of time to work out. But I've been shocked when it's "magic" and it's nice chemistry and heat and things flow organically that's awesome.
