Now, I'm afraid there is one thing I'm not fond of about him too though. Even though he is great at finding doctrine, much like the essay by Mackelprang, he likes to add his own opinions in every now and again. For example, he wrote in one of his posts that some women are not sexually fulfilled until they have experienced an orgasm while giving birth. Though there Are accounts of this happening, in my opinion the whole thing is absolute nonsense.
So, as to the blog LDS Marriage Bed, I'd say take the doctrine he presents and dismiss the opinions you don't agree with. CoachSam's blog really is a great source of information, without of which I would not have as much information as I do now.
