My standard response is:
The ultimate GFE will go all the way to PSE to please her man.
Meaning specifically that the more romantic, intimate activities per the majority of posts on this topic over the years are relegated to GFE status: kissing, cuddling, etc...
PSE is generally referencing more "hardcore" activities such as anal, CIM, etc...
I just do it all therefore negating the need for labels or limitations. LOL But, some fetishes aren't really easily defined since they run the gamut depending on the particular interests involved. If a guy's only interest in feet is to see his woman wearing sexy shoes, that could be GFE; however, if he wants to lick the soles of the shoes & worship her feet or be trampled by them, that would fall into the PSE category to most. *sigh*
Smokin Joe's right, too, cuz most GFE's aren't going to be the dirty-talkin' slut-puppies many would apply to a PSE type. You also have to take into account that some are not as adventurous about sex as others.
Sometimes I think the subjective topics should have stickies. lol Always good comments no matter what your take may be. It's all good!
