This is basically the concept of running a marathon with your
penis. This can either be done solo (lubricant advised) or with a partner. The idea is to gain enough endurance and strength so that you can go a long way in such a
small environment.
First we must define what a "marathon" is; a marathon is the longest considered running competition where competitors run 42195 meters. With our
penis, this
will feel
like an eternity. Here we define the formula to find out how many strokes are needed for a complete marathon run. We assume there is no friction and the receiving party is eligible to take in the whole mass and length of the penis.
Strokes needed = 42195000/(penis length(cm)*2)
For example, a penis with a length of 15 cm,
will need to stroke (in and out, or for single
player experience up and down) for 140650. Since strokes are integers, if your solution is a non-integer number, round up.
