Today's Discussion: Is It Proper For A Christian Couple To Watch Porn Together Before Having Sex?

Aproko News Reader post: First of all, let me tell you who I am.

I don't go to church unless its a cross-over night. Thats who I am. You are free to judge me.
Now to the reason behind the question titled above, (Is it proper for a Christian couple to watch porn together before having sex?), last week sunday, in the morning, I was inside my room having my usual sunday rest in preparation for the new week, when the loud speakers of a church adjacent my house started blarring in its typical we-are-doing-sunday-school-service things.

Frustrated and angry at the same time, I grabbed my phone and began to read posts on Aproko News. Suddenly, I heard someone, probably from the congregation, asking the sunday school teacher the question I posted above and that was what caught my interest. I was curious to know what answer the teacher would give.
But unfortunately, I couldn't hear anything again. I guess the teacher had decided to answer the question without using microphone.

So, can someone help me to answer that question? Biblically or Morally. Thanks!
