many guys, including myself, enjoy pleasuring the ladies, and I do it pretty much every time I see someone.  It is true, some ladies do not like or allow it, but I think the majority enjoy it.  And yes, it is probably considered part of the complete GFE, but that doesn't mean they can't enjoy it as well.

As you surmised, it is a very common part of the GFE menu.

Cunnilingus is on the menu of almost every full GFE provider. Like you said, it is mentioned in most of the reviews you have seen so it is very common. Some of the ladies may better answer how much they expect and enjoy it; but from my experience both seem to be true.  
 

his caressing tongue. I have been with a few ladies who just do not reach orgasm but most sure do.

I will admit that spending 2 hours with a guy who does not daty, is not my idea of a great time, but hey....I still got the envelope. If you don't want to daty or kiss, look for FBSM providers. Usually, they are much cheaper and you can skip all the bs.

I agree that it is part of the gfe menu, and most seem to enjoy it and appreciate the effort. That said, if it isn't your bag, a good provider will be fine with that, too.

that the guys do it during the time with me, but not all do it lol!!

I try to make it clear I want it and love it though!

Daty

It is my personal favorite!
