Pussy per Square Inch. This is an international standardized unit of measurement for square inch of pussy applied to square inch of penis/penii upon penetration. Higher PSI is related to but not conclusive of: better sex, increased number of orgasms, increased intensity, more sexual partners, and a higher probability of contracting an STD. Queefs are also more present in a female with higher PSI, although no direct correlation has been found. The mathematics to define PSI are listed below:

(Penis(Surface Area)/Vagina(Surface Area))*((Penis(Circ)-Vagina(Circ))/100)*Penis(Circ)*Penis (Length)*(Penis(Length)-Vagina(Depth)/100))

Example Math:
Jew Penis: Length: 10inches Circumference: 9.42 inches Surface Area 94.2 inches squared

Twelve Year Old Vietnamese Girl: Depth: 3.5 inches Circumference: 3.14 Inches Surface Area: 10.99
8.6*.063*94.2*.065 = 3.31

In this example, the Jew Penis would feel the pressure of 3 normal pussies on his erect penis during intercourse. This would be amazing.
No children were harmed in figuring out this information.
I could never get with a Jew Penis again. Last time there was so much PSI I wish I had a blow off valve.

I really want to rail that girl over there and take her for a ride. I feel like my boost meter could hit over 10 PSI.

So what do you think our PSI would be baby?

I may not be that big, but I'm an expert with Maths and can tell with your small vagina there would be plenty of PSI.

OH MY PSI. It's over 9000!

Fur and Loathing in Miami: That fox and cat managed to achieve 12 PSI through strategically places holes in their fur suits.

That can't be right, my PSI is reading less than one with an Asian girl. Shit, I should go to the doctor tomorrow.
