As with shop assistants, nurses, teacher, taxi drivers etc there is a wide range of individuals providing a wide range of quality of services and a wide range of services.
There are those SPs who are in it to earn as much as possible in as short a time as possible. They'll want you in and out of the door asap. The condom will be on you before you have half a hint of a stiffy. There'll be no touching here, no touching there - certainly no hint of intimacy. They'll groan and moan, never get wet, use loads of lube and never come. They are a sexual production line. Many of these are young.
Then there are some others - older in my experience - who have a "proper" job - who are in it for some money but also for an adventure and their own sexual satisfaction. They'll chat, some of them really will snog, and you might make a genuine connection with them as real people. They'll take a genuine interest in you and when you see them again they'll remember you and something about you. Some may only see one or two punters a week and never more than one a day. I've had one where a 90 minute meeting became 3 hours.
So let's not label all SPs in the same way. There's the full range out there and research will help you find what it is your looking for.
There are, judging from punters' reports, a range of punters. Some want a cheap as possible 15 minute pump and dump - essentially using the girl as a living fleshlight. At the other end are punters prepared to spend good money to see a SP for an hour or even longer looking for an experience with some variety and intimacy where the SP's needs might also be met. I'm one of these and fortunately can afford to be one.
So you have to decide what it is you want from any meeting.
Just my thoughts and experience of over 40 years off and on in this hobby.
