In old days they used to say that is Bi sex born ! Means they are born with birth issue ! since they have a penis and vag! But now its an erotic thing !
As far as I know, it's just that they have a larger amount of testosterone so most probably have no problems. I'm sure that there might be some that do but I wouldn't think it's the average for big clited women and would be a combination of things rather than just the big clit alone. If someone knows the actual biology behind it and I'm wrong then please do correct me.
