GFE just means anything that makes you feel like you are with your girlfriend as opposed to a sex worker. Many sex workers don't kiss but you would certainly expect your GF to kiss, so yes, dfk is often one example of GFE. BBFS could be a another example too...there's always a risk when you hobby, whether you get GFE or not. You can reduce your risk by seeing low mileage girls at semi-legits but the risk will always be there...if you don't want risk, just stick with a basic hj.
PSE is Porn Star Experience, i.e. hard core sex like what you see in porn movies...
I'm an old man...probably too old to be hobbying.
