According to studies, average dick length is about 5.5" give or take, and just under 5" in girth.
Scientist measure length by pressing a ruler into the pubic bone above the penis and measuring along the top.
Guys usually measure their dick along the underside starting at their anus, and then add 1.5" to that measurement.
How many women claim they have fucked guys with 8"+ dicks. Less than 1% of guys are that big. Either women are terrible at estimating length or their boyfriends lie to them.
Tbombz would love to have the "measuring" job
