Female Sexual Response
So how similar is the female sexual response to the male? For some guys, it
may be surprising to find out just how similar we are to the woman in our life
in spite of how we often look very differently at sex. Yes, there is an
emotional overlay to making love for a woman that is generally not there for
guys. But underneath we not as different as it might first appear.
For example, researchers found that NOS, the enzyme that Viagra acts upon, was
present in various critical regions of the clitoris.  Furthermore, it
was found that clitoral erections occurred through "nitric oxide and
cGMP-stimulated activation of BKCa channels."  The significance? This
is the same basic pathway for a penile erection.
Clitoral blood flow and smooth muscle response is considered critical by
researchers to the female sexual response. 
I discuss, for example, some of these similarities in my discussion on the
G-Spot, where I mention how researchers have found that female genitalia has
abundant erectile tissues similar to a male. I elaborate on this even
further in my link on Females and Viagra, where science has shown that in many
cases, females sexuality and be enhanced using the standard blockbuster PDE5
inhibitors that have taken the male world by storm.
Furthermore, almost all of the risk factors for female sexual dysfunction, high
blood pressure, endothelial dysfunction, cardiovascular disease, being
overweight, etc., are also risk factors for us guys as well.
And I have already shown how females are very much visually stimulated as well.
In other words, Looks and Appearance Are Very
Important to Females as well.
So what does all this mean? If you can understand and satisy the emotional
component of the woman in your life, then underneath you are not facing the
Unsolvable Mystery. Underneath it all, she is remarkably similar to you in
many key ways.
