How long do you masturbate?

It's a very tedious thing to explain, but this about sums it up... "stroke(length+speed)/hand cramp" so... anywhere from 30-45 minutes depending on certain variables.

4 and a half seconds.

Usually 10 - 15 minutes. Sometimes it can take 20 - 30; depends on if I have distractions or not. Can finish in 5 if I need to.

Could be hours or could be just a few minutes
