The earth circumference is around 40.000 km.
If it takes you 1:30 min to complete 1 single stroke that means your hand can travel 80.000 km in that time.
That means you move your hand at a speed around 890 km/s, which is more than 10x higher the re-entry speed of spacecrafts.
This implies your hand (and probably dick) should be burned into nothing by friction if you ever decide to rub one out.
Just thought i'd warn you.
