Animals... Wild.. Uncontrollable... Following their instincts...
Now, would you think an animal can feel 'raped'...? To be very honest I sort of thought animals would like anything that feels good (unless I guess it doesn't).
But apparently they don't.
To be more specific, in some duck species female ducks have developed an
elaborate 'anti-rape' mechanism. It seems that they are often approached by aggressive (undesired) male ducks with malicious intentions and finding no escape... :(
So, (it seems) they have developed certain sacks/dead ends in their vagina... Once the 'aggressor' is led into those their sperm is practically wasted.
Who would have thought...!
If you want to know more check out this article.
“Despite the fact that most water fowl form monogamous pairs, forced copulations by other males — the avian equivalent of rape — are common in many water fowl, [...]. The length of the phallus of a species is strongly correlated with the frequency of forced copulations.” - P. Brennan
I leave the conclusions up to you.
