Her blog highlights an area often overlooked during intimate moments.  

From a structural standpoint, the area under the perineum links to the the bottom of the clitoral legs/bulbs.

This is analogous to the man's corpus cavernosum.  Just as squeezing the base of his penis can heighten the orgasmic feeling from increasing the pressure in the head/shaft, so too can her orgasmic feelings be intensified by the right amount of pressure. (The surface skin in the perineum area has a lot of nerve endings, so varying from light touch to firm pressure can bring about even more pleasurable feelings.)

I've been giving "taint' massages for years and honestly did not realize this sweet spot was generally 'undiscovered'.  Some women like being massaged there, typically for me using just the thumb, while others outright reject the approach.  Of course some women are wary - until they appreciate that my goal is not to enter the alternate opening.  What happens after the taint massage is usually dictated by the recipient's response, which can lead elsewhere, or nowhere.  I believe the key to warming up the subject is not to make the taint the target, rather incorporating it into your overall massage of the mid-section, including ass cheeks and the environs.

Lick, lick, rub, rub, press, press
Yumm, yumm! I hope that would make (or help make) her squirt!
