I would guess that over the nearly 60 years that I have been jacking off, a vast majority of the cums have been while sitting on the toilet. For the past 10 years or so, I have not wasted a drop of my cum. 90% of it goes into my hand and then into my mouth.
The other 10% goes into Sis's pussy or mouth or onto photos that people want decorated and sent back to them. My wife and I started doing that about 7 years ago.
Some other common places would be in bed, in the shower and in front of the computer. Those are only the times it has been a solo act. Having been married 4 years the first time and 40+ years the second time, I couldn't even imagine all the places that my wife and I have masturbated together. Since my wife passed away in 2006, I have been seeing her widowed sister a few times a year and when we are not fucking or doing oral, we enjoy mutual jacking and jilling.
