Ohhhhh, baby! Yeah! That’s right- Deeper! Deeper! Grab my ass! Harder! Yeah, pinch my nipples! Don’t stop… Don’t stop!
The capacity to become sexually aroused just for pleasure seems to be unique to humans. Anatomic and reproductive differences notwithstanding, women and men are more alike than different in their physiologic response to sexual excitement. Wet and slippery or thick, wide and hard your unique physical response is the same whether the sexual stimulation is fantasy, yummy coitus, or masturbation of either the mechanical or manual variety (for you do-it-yourselfers). As for the anatomic differences, let’s start with that clitoris demurely recessed behind a protective layering of skin and fat.
If you pull gently on the hood covering the clit you can see the glans or tip more clearly. It looks a little like the eraser at the tip of a pencil only pinker and smaller. The tip is very sensitive so be gentle and sweet when it is all exposed and vulnerable. The clitoris secretes a cheeselike fatty substance called smegma. Smegma has a distinctive odor that serves as a pheromone, an organic compound that provides communication with other members of the same species. In this case smegma prompts erotic stimulation in human males.
The labia majora and minora are the two pairs of lips. The larger, hairy lips extend from the top of the clitoris to the perineum (the skin between the vagina and anus). The smaller hairless pair are inside these wrapped around the clitoris and urethra (pee hole). Labia range in size and colour. They can be long and skinny or fat, short, puckered, frilly, curved, dark brown, pink, tawny or shades of grey. The vagina is located in front of the rectum and below the urethra between the base of those warm soft lips. It’s a very supple tube capable of great distention (think descending baby).
About 8 cm long ending at the opening to the cervix, the vaginal walls secret a lubricating moisture – the woman’s first observable reaction to sexual stimulation. This lube is affected by the woman’s cyclical changes creating an atmosphere either congenial or hostile to sperm. It looks, feels and stretches like an egg white around ovulation and is white and sticky pre or post. As sexual excitement progresses lube flows freely and the outer one third of the vagina becomes greatly engorged as the inner 2 thirds lengthen and distend pushing the cervix and uterus in optimal position for fertilization (so cum prepared).
Speaking of sperm, it travels at the rate of 3 – 3.5 mm per minute and can survive in the vagina for about 2 days. Each ejaculation consists of 3 or 4 ml of fluid and contains about 300 million sperm suspended in the secretion. Sperm is formed in the testis found inside a pouch like receptacle called the scrotum. Each testicle is a laterally flattened oval shape, about 4cm long and is enclosed in a thick fibrous sheath. The internal pressure is very high as this, for some reason, is necessary for sperm production. Inside there are 1-3 finely coiled sperm making tubes and cells that produce testosterone, explaining the condition of eunichism following castration – ballus chopus offus.
The size and shape of the scrotum changes due to the action of smooth muscle fibres below the skin. When these fibres are warm and relaxed the skin of the scrotum is smooth but when it is cold they contract and cause the skin to wrinkle. The sperm discharges out of the testis into long coiled tubes called the epididymis. These tightly coiled tubes are about 6 metres long! Would a cut testicle explode like a golf ball? Upon ejaculation semen travels from the epididymous to the vas deferens, a highly muscular thick walled tube. These muscle walls produce strong contractions during ejaculation forcing sperm out of the vas deferens into the urethra and beyond.
Ejaculation is a reflex, normally preceded by erection which is maintained by the help of an abundance of erectile tissue in the area, several muscle groups and arteries engorged with blood. Pressure in the arteries to the penis cause them to distend while muscles around veins contract to prevent blood from leaving the penis, something I think we are all grateful for.
Why am I telling you all this? Cuz’ next time we meet we’re gonna slip, slide and stroke our way through the ups and downs, ins and outs of a good hand job and I knew you’d want to have a firm grasp of the subject before we start. Until next time, get some lube, preferably a tasty one.
