PG 18, learning something new on a certain male organ

I think I am late in the news or I didn't followed closely enough in biology class.  It seems that some species have a penis bone.  I found it in this video called «Why Don't Human Have a Penis Bone?»:

This other one:have the same topic https://www.youtube.com/watch?v=l3lr2_DGJjw.  Same title but the second one is from SciShow.  I am tempted to put the one done with the SciShow a bit more credibility.  Must be the name of the channel that gvies me more confidence in this topic.  I wonder if one channel copied the other or they did that topic independently.

Well, It is nice to have two videos on the same topic.  It give some credibility on the content.  Okay, youtube video is not the best place to get valid facts.  In the two videos, if I remember well, they talk of the baculum, the more scientific term of penis bone.  So, I took up myvarious  paper verions of the dictionary.  I didn't found what I am searching on.  Even my encyclopeaedic dictionary didn't have it.  Time to invest in an encyclopeaedia, I guess.  Or I go to the library to find the answer.  I know that modern time librarians are not the old maid of older times.  I just feel a bit blushing to talk about that.  I am not used to my local library, so, it is inevitable that I have to ask about the encyclopeaedia.  The librarian may be curious on why I need to consult those books.  There is the problem.  Even if sex is now not taboo, I still have a bit of blushing when it comes to that topic of anatomy.    So, I know that I am sky about exposing some interest in intimate biology.  When it comes to a public area, it is a bit more ardeous to get the topic out.  Must be a cultural thing.

I have done a research with the word «baculum» on google and there is a few scientific articles on the topic.  Here is a few: https://www.theguardian.com/science/2016/dec/14/why-dont-humans-have-a-penis-bone-scientists-may-now-know-baculum

Now, with all this useless information, something that I would like to learn sooner, I am tempted to use it in a story.  I gues it would be an selling story.  Sex and sexality are a seller.
