Need advice...

I am LDS and I have been married for 6 years now. I am very happy in my marriage and we have a healthy sex life. For me however it takes a long time to get wet and we have to use lube every single time.

So I was wondering if it is ok, by church standards, to read erotica or watch porn before have six with the purpose of getting me aroused for my husband?

Ps. Sorry about how personal this question is, I just dont have anybody else to talk to about this.
