Well said!
With an escort, there isnt alot of mystery, especially with being able to research the details on TERB. You know all about the availability of DFK, DATY, MSOG, BLS, or anything else. You are there for the sex, plain and simple, although some girls are more fun and a better conversationalist than others.
With an MPA, there are so many more variables in the equation, all you can be sure of is the massage and release. There is often alot more available, but that information is carefully guarded, so its like scratching your lottery ticket to see if you might get lucky and win big!
The thrill is in the chase... the "woo factor"... can you get more than the average client.
And to be honest, with an SP you need to perform! Sometimes its nice to just be pampered and pleased. I dont get any less satisfaction with an MPA, it all depends on what type of fun I am in the mood for.
