When I first started living with my present SO, we had a discussion about masturbatory frequencies, and since mine was by far the more prolific, I couldn't help but give a guesstimate for my lifetime total. Needless to say, from my SO's perspective, this was an astounding number. Using a consertive estimate of an average of 5 times a week for the last 26 years, a very rough, but up to date total would be:

5 * 52 * 26 = 6,760.

So any of you old fart wankers and wankettes out there care to give an estimate?
