2(sq rt of (X-15)) = Y

X = your age
Y = no of sexual partners (nearest whole number)

This is the formula to calculate the normal number of sexual partners one should have had for a given age (discounting escorts/clients of course).

I'm 87 yrs old so Y for me comes out to be 17. Wow! 17? I've a way to go before I get there. A long marriage to my poor dear Penelope put me lagging behind from the outset, I'm afraid.

Is it accurate for you?
