I wish there was a universal definition for both! I've heard both so many different ways. To me, GFE is more intimate, lots of DFK, more sensual, love making style. PSE to me should mean BBFS, definitely BBBJ, cof, cim, all that good stuff. However, not everyone agrees on that lol. I'd be curious to know what you're definitions are as you are a smoke show! Tried the link to your site, it did not work for me.
