question about Mity vac cylinder size?

4.75" circumference equals 1.5" diameter.
5" circumference equals 1.6" diameter.

Standard practice is to use a pump cylinder that is .25" bigger in diameter than the thickest part of your erect penis.

If the thickest part of your erect penis is a 5" circumference on a good day, get the 2" diameter MityVac or ProVac
