I've been eagerly reading this blog on vaginismus. The writer has been married over a year without sex. She has visited a sex therapy clinic, and seems to be making progress.
Many of the commenters blame the writer's religion for her problems. When bystanders are confronted with a really difficult situation, some will go to extreme lengths to convince themselves that it could never happen to them. They may think that being in an unconsummated marriage for over a year seems so extremely difficult, there must be some reason that it happened to her and not to other people they know. Presumably it could happen to anyone.
Some criticisms relate to ignorance, but there are so many issues that people never need to think about. How many women know what the hymen looks like? I study sexual initiation, but the anatomical details have never been relevant to me professionally, and I didn't know what the hymen looked like until I saw the above pictures.
