Need some help understanding something

I wouldn't consider it the same as watching porn; however, I think for some it can be a Psub.

 

Almost porn, I used to jack off reading some.

 

If we read something that describes a certain place, a certain action or whatsoever, we automatically try to imagine whats going on in pictures.
If you start reading erotic literature, guess what happens.
Your subconscious mind can´t differ if your imagination is real or just pictures produced by your mind.
That´s why phantasizing is bad, but having a lot of details, which the author delivers, you gonna build pretty realsitic pictures in your head.

So I wouldn´t recommend doing it.

 

Seeing how close you can get to the edge will guarantee a fall.

A better question is, "Will it help you build a growing relationship with a SO?"
