What I think the best girth is.
Just like men women come in different sizes.but also just like men majority women fall within small margin.most women fall within 1 SD of the average.I searched for vagina size but I could only find statistics from non aroused state.1 SD over/under average was 8%.84% of women have vagina
Size -1SD or bigger
68% within 1 SD of average (34% 0 to -1 SD and 34% 0 to +1.0 SD)
27% within 1-2 SD of average
5% 2-3 SD
<0.1% 3-4 sd
My goal girth is 8% less then what average female can take comfortable without hours foreplay or very lots of lubricants lol. That meas 50+34%=84% of women can take much more then average (the girth Queens lol). Some of the 13.5% that have vagina size -1 to -2 can take it too with long foreplay and the -2 or smaller will be feld fulled by mr average or smaller lol.
I thin average (non east asian girl can take) can take 6 3/8 girth or so but I’m not totally sure.1 sd less is like 5 7/8 girth.
