A Living Exclamation Point Of Flesh

An exclamation point is vertical.      
Likewise with an erect penis.      
An exclamation point is put at the end        
Of a sentence to convey emphasis.      
Likewise,when a penis goes from soft to hard,      
from hanging down to standing upright,      
It is emphasizing something!       
       
Yes, an erection can be thought of        
As a living exclamation point of flesh.     
       
So what is the implicit sentence    
That an erect penis belongs at the end of,
Punctuating it, so to speak?     
   
It is this:      
"I am a man(a husband)      
And I am ready to make love(to my wife)!
