I do not have lumbar issues (that I know of) but when my pain issues started I noticed exactly what you are describing.  I never put the two together.  It doesn't matter to me now though, I can't even pleasure myslef due to the pain.  Sex is completely out of the question. 
 
I hope someone else might chime in.  It is interesting.
