An Australian mathematician has come up with an Optimal Lurve Procedure, aka the "12 Bonk Rule".
This involves making a checklist of desirable qualities, going through 12 lovers testing each one against the list, then getting serious from number 13 onwards.
Nothing like a properly tested Procedure.
"Darling, d'you think it's too early in our relationship to calibrate?"
At my age and given my recent scoring averages, I'll be in a Zimmer frame before I've got through the test batch. So I'll stick with the "1 Bonk Rule", the next gal to put out gets me for life.
The picture shows a division of Valentine tanks, because my love life is tanking. Geddit? GSOH essential, what what?
Own hair and teeth.
