For your desire to seperate the inherint preverse nature of BDSM and at the same time keep in line with your relegious beliefs. I believe you will need to walk a very thin line. Since you have lots of experience, you have lots of knowledge and ability to bring to the "battle" if you will. If I were in your shoes (and I was very much so, and decided to not pursue my religious beliefs) I would read historical non-fiction accounts and self help novles. Also, honing your leather making skills would be a rather clean road to maintain. My biggest piece of advise I can give you though is to refrain from erotica/pornography portions of BDSM. They are based simply in fantasy, and have little value (except to foster ideas) to your BDSM side of your life.

Good luck in your endevors, the road you travel will be difficult. You might be able to find some helpful answers by typing "bible BDSM" in google. I truely do wish you the best.
