How Long Is Enough?

Specifically, how long should it be for it to be a good roll in the hay?

If the discussion only involves the time of total penis insertion, the average runs about 5.4 minutes. Okay, that's 324 seconds just when it's in the honey pot. 

too short   1-2 minutes
adequate   3-7 minutes
desirable   7-13 minutes
too long     10-30 minutes

But these times refer specifically to how long the penis is actually engaged in place.   Do be a real dear: do sufficient preparatory work. Like 20 minutes' worth might be a good idea.

Once a guy took 35 minutes inside me. That was the only time. I was sore as can be, and exhausted. Damned heavy-handed tree-hugger!
