The same as girls do...
For Asian man, it will be around 1 inch
For Western man, that will be around 1.5 to 2 inch
It means you're making a big change.
measure her. if its over her waist size, she's got a big butt. not always a bad thing tho... ;) Big butts are cute you shoudnt be worried about if your girlfriend has a big butt mine dose she weighs about 160 pounds big butts look great on women especially in tight jeans or really short shorts my girl wears these super tight shorts its amazing how she stuffs it all in there
its an opinion not fact
Not in its entirety.
They run small
Generally, it can't be "too big". Your anal sphincter can stretch a looooot. Try eating more fibre
as big as a mans hand
As big as a mans thumb.
That is disgusting. I hope not.
How big do you want it to grow? There is a physical limit but if you take it slowly you can expand your anus to quite massive proportions. It is quite common for people to fit a partners entire fist in their anus and some people go even further using giant sex toys. It is largely a question of, how far do you want to go?
depends really. if 20 atleast a bit big and fiem
Microscopic.
about the size of a mans face
i would say about 6.5
Your question is not specific but if you mean enlarge, it is not a good idea.
only if their really big
Depends on how big you stretch to.
