It takes to serve the first cup.  If it takes 20 minutes for the first, the second normally takes longer to brew.  Dependent on how much time is left due to other activities... There may not be time.  So there is no one correct answer.

I never thought of GFE as 2 pops.  What I sell is time and if you can pop twice in the agareed upon time, then great. If we're out of time then the second pop isn't going to happen

The definitions of GFE and PSE vary from person to person and forum to forum.

At least 2 cups of Joe!

Unless the coffee is to strong lmfao!

I always thought that GFE meant Girl Friend Experience and PSE meant Porn Star Experience. GFE involves kissing and making out leading up to the main event, just as one would do with one's girl friend.. PSE, I believe, means skip the preliminaries and lets get to it.

I never knew it involved counting cups.
