Cara Mengukur Mr. P yang Benar

cara ngukur diameter yang benar dengan menggunakan
pita yang dilingkarkan ke mr.p saat tegang banget
apalagi pas mo muncr*t (hahaha... boleh dong nambah2)
hasilnya dibagi dengan bilangan pi(3.142) maka
didapatlah diameter mr.p -> menurut

...A good method to measure yourself is to use a
fabric tape measure, place it behind your balls and
around the top of your cock, close to your body. Once
you have this measurement you then need to divide it
by 3.142 to give you the diameter of the minimum size
ring for you. It is very important that you do not
wear a cock ring which is too small for you, it could
cause circulation problems and tissue damage...
