Just watched a Mythbusters “do bigger breasts mean bigger tips”. They got a female member of the team to work the same shift in a coffee shop - was disguised, wore the same outfit each day (tight top, no cleavage) - no padding the first shift, medium padding the second shift and large padding the last shift.
She received significantly more tips when she wore the big padding - it was interesting to see how the male customers reacted on the hidden camera too.
Also, FAT - fat has a lot to do with the effective size, penis length for the men, and depth needed by the woman.
Layers of fat on the pubis can easily lose a man two inches or more - the penis starts at the pubis bone, but if you have two inches of fat then the first two inches of penis are buried.
Likewise on women - say a particular women has a depth of 6-7” but if she has 2” layers of fat on her pubis then she needs an 8-9” penis to hit bottom.
If a husband and wife both have excess fat on the pubis they could ’losing’ as much as 4 inches of effective penis length.
If you look at photos of men with micro-penises it is common that they are overweight. If they were to lose that weight they would probably find that their penis is much longer than they think.
