AMAZING GRACE
Dr. Grace Carole F. Beltran
The anatomy and physiology 
of vaginal orgasm, part 2


DURING sexual intimacy, touch or physical contact on or around the genitals excites sensorial receptors in the skin. This excitation travels through sensory nerves to a reflex center in the lower part of the spinal cord. This center sends messages to the muscles around the arterial walls of your genitals, telling them to relax. As the muscles relax, a lot of blood flows into the arteries of the genitals and results in sexually prepped genitals. In women the vagina becomes swollen, red and lubricated. In men, the penis becomes erect. During this time sensorial impulses shoot up your spinal cord to special parts of your brain called the sensory cortex and the limbic system (the emotional brain), which is when you experience the euphoria of reaching Mt. Orgasmus.

At the said point, other areas of the brain and nervous system join the fray, recruiting the hypothalamus and the autonomic nervous system results in more stimulation and heightened sexual arousal. The skin becomes more sensitive, the heart rate and breathing speeds up. Blood gathers in breast tissue and the genitals. Sex hormones (oxytocin, dopamine, norepinephrine, endorphins, estrogen, testosterone) are released into the blood stream and orgasm results once the relay of nerve signals escalates to a point where a release (built-up of sexual tension) is inevitable.

An intact brain, spinal cord, autonomic nervous system and genitals are a must for the success of sexual orgasm. For the males this is not a problem. However for females, lost of muscle tone in the genitalia after childbirth can result in failure to achieve sexual satisfaction. Exercises to strengthen the female’s pubococcygeus muscle (PC) is recommended once this part of the genitals become too compromised due to too much stretching. A surgical procedure called vaginoplasty and/or labiaplasty might be necessary. A strong PC muscle will heighten genital sensitivity, intensify sexual gratification and orgasmic potential.

To exercise simply pretend you are stopping a pee. Once you understand where the muscle is, you can practice with repetitions (fast or long and slow) while on your vehicle to work, in the office or while watching or reading your favorite show or book.
