Receiving oral sex is great for many reasons which need no explanation, but what about giving oral sex? Can a person find pleasure in performing an act which, on the surface, appears to be so one sided? Yes, of course. But perhaps it is not entirely for the altruistic reasons you suspect. Let me back up to get a running start at this.
You’ve Got A Lot Of Nerve
The head of a woman’s clitoris (just the visible part) is packed with 8000 sensory nerve endings (interestingly, that’s about twice the number in an entire penis) and, when it is stimulated, every one of those nerves sends signals to the brain in unison where they get processed by her Pleasure Center and activate a feedback loop which makes her desire more of the same (I’m not making this up). Blood flow increases to the area to keep the hard working nerve cells supplied with oxygen and energy so they can continue their rapid fire bombardment of her increasingly aroused brain. This goes on until the stimulation becomes overwhelming, areas of the brain in charge of reason and behavioral control flicker off, and voilà… orgasm.
While I am certain I just oversimplified a very complex physiology, it seems to me that the volume of [sensory] neural network traffic sent brainward is directly correlated with a person’s perception of physical pleasure. Like, the more nerve signals terminating in, and electrifying, the brain the greater the reward. In the example above, her nerve packed clitoris would be like an exposed electrical terminal on a heavy gauge cable run straight through her body and grounded in her head. It’s a powerful up-link directly to her Pleasure Center with the potential to light it up.
There are other parts of the body which are highly innervated as well and, interestingly, many are associated with sexual pleasure and/or arousal; lips, tongue, ear lobes, finger tips, nipples, anus, and genitals among others. Each one capable of pleasurable sensation on its own. Combine simultaneous stimulation of two or three and what happens? Greater pleasure. The more sensory stimulation in, the better the ride. Read that last sentence again and let it sink in.
Come To Your Senses
If you are a normal, healthy human you have five senses; touch, taste, smell, hearing, and vision. From the neck down you have only one of these… touch. Above that you have all five! On top of that neck of yours, you carry around a sensory powerhouse capable of processing the world around you with 500% more clarity than the rest of you. There is great variety in the sensory information your face can send to your brain. Can these senses produce pleasure? Of course! You enjoy the taste of many foods, smells that trigger memory or emotion, and lighting or visual cues which can calm or excite. Each floods the brain with stimulation and involving these senses directly in sexual play (getting your face right in there) can elicit feelings of pleasure.
Soak It All In
Additionally, your sinuses and mouth are lined with thin tissue permeable to hormones in your partners sexual juices and pheromones in their excited scent. These go straight to your blood and quickly find receptors capable of putting them to work affecting your state of mind. You are the chemistry of your body and sexual contact facilitates an intermingling capable of orchestrating incredible convergence of bodies and minds. If you’ve ever had really great sex then you are probably familiar with this synergy.
Not A Selfless Act
Personally, I get great pleasure from burying my face between Jane’s legs. Her obvious arousal is a real turn on but I am convinced there is more to it than just that. I taste, I smell, I see, my lips and tongue feel as I trace lines through her folds and kiss her sensitive clit. I drink her in, both figuratively and literally, I get drunk on her lust and satisfaction from her orgasm. It’s a sexual experience I crave like many others, I desire it because it brings me pleasure. It’s not selfless.
