I have never been a fan of the "you can look but you can't touch". That's why i have never plunged full throttle into pornography (that plus i am afraid i would like it too much and end up in a 12 step program! :) Pornography and Erotica are pointers. They are road signs. They point to the destination but are unsettling as destinations in and of themselves (at least for me). It's like getting stuck at the roadside attraction on your way to Disney World.
God? Sex? He invented it! Sex, making love, is emotional communion. It is as close as you can get to another person (and God) in many ways. It is true union. The shame is that the 'church' has missed this for many years. Stop in any town and ask where the people who have crazy, intimate, passionate sex is and i doubt they point to the local church but isn't that how it should be...
A friend of mine is proud that i have never been to a gentleman's club (and all my buddies want to be the first to take me!) In reality, it is as much about not wanting to torture myself (and spending money to do it!) as it is anything else. C.S. Lewis said its like putting a steak on the stage and having people salivate over it. What is the point if you can't eat it! (Yes, i know what you are thinking! :)
Maybe erotica tends to arouse and point to the object where pornography attempts to become the object on its own. I don't know, i am so confused. All i know is anything that stirs the body, mind, and spirit to a large degree has to point somewhere.
