That's a very good, if depressing article.
I remember going to the GP not long after I became sexually active, and mentioning (I think I'd gone to get the pill) that sex hurt. She suggested reading The Joy of Sex. 

It wasn't till years later that I stumbled upon the word "vaginismus". Fortunately (or fortuitously) I inadvertently cured myself; the pill did not agree with me, so after a protracted fight with the doctors (they don't like you not taking hormonal contraception) I managed to find a family planning clinic prepared to give me a diagphragm. In learning to insert it correctly, I learned to relax the relevant muscles - I had in fact done what is the normal first line of treatment for vaginismus, namely getting used to a set of dilators of varying sizes! The other thing in my favour was that having grown up yonks ago when sexual mores were rather more conservative, my first boyfriend and I "fooled around" for several months before trying PIV - so I knew what it was to orgasm, and knew that PIV wasn't meant to feel like this.
The other thing that occurs to me is that I have never liked giving oral - I did it because it was expected of me. It makes me gag, gives me a sore jaw, and I get no pleasure from it. I know other women say they like bringing pleasure to their partner, or that the feeling of power turns them on, but I'm completely "meh" about it - it lacks the reciprocity of a decent sexual encounter.
