"Penis length IRL = 60.2*3.38 = 203.5mm = 8.01"This is not the full palm of the woman. 2.91" (74mm) is the average female hand breadth, and hand breadth is the distance bewteen the two outermost points of the palm, i.e. a lot more than the distance across the fingers.

Distance across her fingers IRL = 74*74/91 = 60.2mm
Penis to hand ratio = 169/50 = 3.38
Penis length IRL = 60.2*3.38 = 203.5mm = 8.01"
FWIW.
Dude, you're a joke.
