I'm really not looking for extras (though if offered, I'd most likely gladly partake).
What I *don't* want is a sub-par experience where I find that I "missed out" on what would be considered normal, par-for-the-course activities because the girl I'm with was having a bad day, didn't find me attractive, or because I didn't initiate, etc.
My understanding is some girls are more prone to that behaviour than others - and this applies to both MPAs as well as SPs.. and those are the types I'd prefer to avoid at this point (ie. say girl A provides service ranging from poor->amazing depending on how you click, vs. girl B who consistently provides very good, but not amazing, service.. I'd rather go with girl B at this point)
As for an SP, well, I'm working my way up there..
