>>14402513theoretically the female asshole can take much more than the male asshole because the hips is much wider and larger (for obvious reproductive reasons).
Still, I come across more frequently males fitting much larger objects inside their recta than females. Why is that? I think it is pure probabilistics and psychologie. Males, at large, are more perverted and guided by measures (like how much of a diameter in inches I fit into my asshole). Some also seem more self-harmful (like having the wish to be incontinent) than women.
So in theory women should be able to take more but you will never come across a woman that can take as much as a random gay dude in SF.
