Interesting. I think I’ve read that somewhere before.
So I’m thinking you’d have to have a penis under 4 inches NBP for you have something to worry about (that should account for that 5% of 6% of the women, the other 1% being size queens). I say NBP because of what you point out in (1), it’s hard to believe that only 2.5% of men have a penis over 6.9”… but it is easy for me to believe that only 2.5% of men have a penis over 7.5” BPEL.
PS. I seem to love beating dead horses.
