You might blush in reading a few of these websites :)

http://www.themarriagebed.com/ - my husband recommended this website to me in our during our engagement. Most likely he did this so that I would stumble across the section called, "Sex for the Clueless Bride." :) Some of it was shocking for me at first, but now I can only say that I am very thankful I read it! This couple also has individual websites, the generous wife and the generous husband.
http://www.sexuallyconfidentwife.com/blog/ - Shannon Ethridge has a blog site that accompanies her latest book, "Sexually Confident Wife." The blog includes discussions on topics such as oral sex and masturbation. (Gasp!) BUT both of these are areas we need to get comfortable talking about with our husbands to be.
http://www.intimacy4us.com/ -I get the magazine, "Intimacy" in South Africa, but they have an excellent website as well. They give advice on marriage and intimacy all from a Christian perspective. Let me just say they don’t hold anything back when it comes to talking about sex!! I'm sure you will find something interesting to read here, check it out!
