How did the first humans figure out how to procreate?

ven back then he was smarter than you .

fuckin stupid scientists hadnt even invented KY yet, let alone astroglide.

so they can procreate?  

Or did your dad have to pour some of his shit into a tube?

Are you a scientist?  
 Many guys who depend on someone leading them every step they take become  
scientists so they can research with other guys  which way to go .  
   
  The first time I peeked under a  GF's  skirt I noticed she had an extra hole .
 I wondered what that was for .  
 While kissing her I made  a smooth  move  
 Slipped  my finger down below to roam  
 My finger checked that top hole round and round  
Hoping  she wasn't a  double barrel brown eye girl .  
  When my finger came up smelling like a rose .  
 I licked her sweet extra  hole ,  
 Seventeen minutes  later she screamed out loud  
 "That holes where your dick needs to go"  
   
 

Dad always use to tell me, that my better half ran down his leg.  

If you have seen any professors doing their work, you'd realize that they do independe research.  
They don't sit around waiting for other people to write them instructions. They pioneer their own work. That's what being a scientist entails, doing ORIGINAL work noone else has done and being an expert in their field.  

That science does not have a definite answer to yet  
but does have a hypothesis...  

your best bet in finding the answer to anything.  Do you really think that science equates to the answer to everything?  They have never made that claim because science is a mechanism over discovery through persistance through trial and error, mathematically backed conclusions, and the inevitable path to becoming closer to the truth asymptotically as a function of time.  

That movie kind of dealt with this. I think Madison's right- it's instinctive based on pheromones and attraction. All you know is that you want to be near that person (sometimes any person). I remember my first stirrings of desire, and at that age I had no idea about the mechanics of it all. The closest thing I could relate to at the time was what we kids called a "TV kiss"- a really loooong kiss. We had no idea there were tongues involved. But you do crave body to body contact. Just like the cats, you'd end up figuring it out eventually.

Game of Thrones protrayed that with my favorite character Daenerys Targaryen  She is traded by her brother to go off and be a bride with this big dick mother-fucker.  On the honeymoon night he bends her over these rocks and she is crying.  And this goes on until she asks a slave girl that she freed to be her handmaid, if she could teach her how to fuck her husband.  The next time he tried to bend her over, she pushed him back and mounted him face to face.  He was in love with her from then on, his moon and stars.~  

I'm sure the fucksticks at the federal level have found money to pay for boner research

see how clueless YOU really are.  In fact stop using your gps to get to incall, stop printing out maps,  let's see how well you find your way LMAO .    

Men like to stick their dicks in warm, soft, tight, often moist places. Women have 3 such places. Procreation was just a by-product trying all the above. I can only imagine what went through the minds of the "first humans" when the female became pregnant, then gave birth. I imagine it could have been pretty comical to us.

Where did the first humans come from?

From PV sex so she said, "the only one getting anything from this is you, try using your tongue and see if that works". Then she cried "Eureka" as her orgasm hit. And like any woman she had to go tell her BFF and it got around.....
