Query: DON'T WASTE YOUR MONEY!!!!!!

Don't buy this book. Huge waste of money and is just basically an advertisement. If you want to learn more about painful sex, you don't need to spend money...there is so much free information on the Internet, not to mention that that this place the authors keep promoting costs an arm and a leg and there are other places you can get even BETTER help for much less!!!! Google Vaginismus treatment and keep your options open before you start refinancing your house!!
