Human body always holds secrets for us. It is such a maze that probably scientists won’t discover everything about it in the next couple of decades.
It has been already revealed, though, that men don’t have a penis bone at all. Researchers could back it up with obvious evidence. So what should men blame for not having a “baculum” (penis bone) even though they used to have one.
It is known that some mammals have evolved not to have a baculum just like humans and some of them still have one.
