Men are from Mars. Women are from Venus.
Nope. All humans have been born on Earth so far. Culturally, men and women may interact as aliens, but anatomically, they are strikingly similar.
Well, men are different than women, right?
Between the sexes, there are more similarities than differences, so I’d go with...
If you're wondering how I think about nerve systems, this diagram might help. Notice the orange highlights, which represent important nitric-oxide-producing nerve systems. Nitric oxide gas can be used (in a basic sense) for pleasure and nurturance, or inflammation and pain.
You see, the gas nitric oxide is important for sexual...
There are three different nerve systems which either suppress, allow, or build sexual arousal. These three nerve systems are all part of the autonomic nervous system which maintains all of our internal functions.
The first system is the Sympathetic Nervous System. It is represented on this diagram in orange/red. The SNS joins...

Sometimes when people experience changes in sensation of the skin of the vulva and bottom, it is useful to know that different nerves (and therefore different nerve pathways) are responsible for sensation in different locations. The right of this map shows the usual sensory nerve distribution and the technical name of the nerves. (Because...
Dear Dr. Myrtle,
Do women really get erections? How can they--they don’t have a penis!
Technically, it isn't a penis that becomes erect. The clitoral caverns inside of the penis are the structures that become engorged and erect. So when the clitoral caverns swell with blood flowing into the clitoris, it pushes on the penis, so that from the...
Dear Dr. Myrtle,
I don’t know whether this is a problem, but I have noticed that when I self-pleasure or have sex, one or both of my testicles "disappear" up into my body. Is this a problem?
When people become sexually aroused, a number of different muscles involuntarily contract, which regulates everything from blood supply to positioning...
Dear Dr. Myrtle,
I know that every woman is built differently. But is a extra large clit a rare thing? Mine kind of looks like the head of a baby boy’s penis and is about 1/2 inch long.
It’s true that the clitoris varies greatly from person to person. Some of it depends on what hormones you were exposed to when you were a fetus, and...
