The married bed
Commenter Alan sends this in:
“The Marriage Bed provides a Christian alternative for married and engaged couples seeking information about marital intimacy. We combine the truth of the Bible with biological facts to educate, edify and minister to those seeking God’s best for their marriage relationship. Whether you are just starting out, have some problems, or just want to improve an already good love life, we offer information and resources on many areas of sexuality and marriage enrichment.”
