Basic Sex Education

I guess I'll start with the male and female reproductive systems.
Information for the section on male and female reproductive systems is taken from: http://www.mypleasure.com/education/sexed/reproduction.asp

The Female Reproductive System

Female genitalia is usually grouped into two types of sex organs: internal and external. External organs include the sensitive and erotic sex organs: mons pubis, v****a, labia majora, labia minora and clitoris (also known collectively as the vulva). Internal organs include the uterus, Fallopian tubes and ovaries, which contain the female's sex cells: the ova, or eggs. Unlike the male, the female does not continue to produce sex cells throughout her life. Rather, each female is born with an individual quantity of unripened eggs already in place. Each month, an egg is released from one of the ovaries and moves into one of the Fallopian tubes, where it travels down towards the uterus. If fertilization occurs, the egg clings to the uterine wall and begins to develop into a fetus, which is nurtured by the rich lining of the uterus for nine months, until it is ready to move down the vaginal canal and into the world. If the egg is not fertilized, it passes out of the uterus through the cervix, along with a portion of the no-longer-necessary uterine membrane the uterus had prepared for fertilization--this is a woman's menstrual period. Most women are also born with a hymen, a thin membrane that lies on the inside of the v****a. Some blood may issue from the tearing of this membrane during first intercourse. Although different cultures may attach an importance to this as a sign of virginity, the hymen often is torn during the course of normal daily activities long before a woman may ever have intercourse.

EDIT 8/24: It's been brought to my attention that the hymen is apparently on the exterior of the v****a, at the vaginal entrance. You can see a picture of it here: http://img.photobucket.com/albums/v600/Nikolita/hymen1.jpg

The Male Reproductive System

The male reproductive system is almost entirely external. The p***s consists of the urethra, the shaft, a number of sensitive nerve endings, and the glans, also known as the head of the p***s, which is covered with the foreskin, a loose layer of skin often surgically removed in a procedure known as circumcision. Testicles (testis singular, testes plural) are the male gonads, the organs that produce sperm. Most men have two testes, which are suspended from the body by the spermatic cord and rest inside the scrotum, a sac that hangs under the p***s. Divided internally into two pouches by a thin membrane, the scrotum is covered by an outer layer of thin, wrinkled skin which in turn covers a layer of muscle, which acts as a protective covering and serves to maintain the testicular temperature at about 2 degrees below abdominal temperature. Sperm is produced in the testes, then travels through the vas deferens, seminal vesicles and prostate; en route, it picks up testosterone, seminal fluid and prostate fluid, all of which combine to form semen. When a man experiences sexual arousal, the p***s fills with blood and becomes erect. At climax, semen, filled with several million sperm, shoots from the urethra and tries to fertilize an egg. If the sperm is successful, a fetus forms over the next several months. If not, it's no big deal for the reproductive system--it produces several billion sperm a day!

Female Orgasm 101

Men, hold on to your hats! You are about to be let in on a whole new world of secrets! A world that has the power to confuse, mystify, and bewilder?

The world of the female orgasm!

The female body is a complex work of art ? beautiful to look at, but difficult to figure out? especially when it comes to orgasm.

Many men find it difficult to understand the female sexual response cycle simply because it differs so much from their own.

Here is a brief overview of what happens during a female orgasm:

- Stimulation of clitoris
- Tension build-up is caused within pelvis
- Tension is finally released and orgasm is experienced
- Series of involuntary (yet pleasurable) muscle contractions sweep through body
- Contractions are felt in the v****a, uterus, and/or rectum
- Unlike with the male orgasm, women have the ability to feel many different types of climaxes. These climaxes are dependent on the types of stimuli used, and whether the orgasm is clitoral or vaginal.

Types of Female Orgasms

The male orgasm is pretty straightforward ? stimulation, arousal, and orgasm.
In any position.

But as usual, the woman is a little more difficult to figure out. Women have a wide array of erogenous zones, the two most popular being the v****a and the clitoris.

Here?s a little introduction to each of these pleasure zones:

CLITORIS:

- Areas above, to the sides, and below the clitoris are highly sensitive
- Its only physical function is to provide sexual pleasure
- Most women claim that the clitoral orgasm is the most intense
- In his book Sexual Behavior on the Human Female (1953), Charles Kinsey found that out of 2700 American women, half received orgasm through clitoral stimulation


VAGINAL:

- Outer third of the v****a is the most sensitive
- Many women claim that it is more difficult to achieve a vaginal orgasm than a clitoral one.
- Freud labeled this type of orgasm as the ?mature? type, whereas the clitoral orgasm was an ?immature? type of sexual experience (A General Introduction to Psychoanalysis, 1916)

It is important to note, however, that one type of orgasm is not better than the other ? they are simply two different ways of experiencing pleasure.

Every woman has her own preference over which orgasm provides the best pleasure.

Men who are striving to please their girlfriends or wives in bed should communicate with their partners to discover:

a) which is easiest for her to achieve
b) which one she prefers in terms of physical pleasure

The man?s goal should be to aim at helping her achieve her well-deserved seconds of complete and utter pleasure.

Thanks a lot for doing this. I learned more in here than I did in the health class at school. (Granted my school is crappy, but still. Useful. And really not the kind of thing I want to randomly walk up to people and ask about.)

Not PG-13!

This picture has the clitoris labelled. It is a part of the female anatomy that is very full of nerve endings. When a baby is developing into a boy or a girl a clitoris is formed and then if the baby is male that part becomes the p***s. It's only known function is sexual pleasure. It looks a bit like a pea when in is erect and has a hood of soft skin that covers it until it becomes erect.

Updated 10/9.

I didn't really know which sticky this would go in, so I just put it here, it seemed best.

I have a few questions that have arisen since my boyfriend and I have started having sex.

1. My boyfriend and I obviously don't have all night, like married couples. But Hollywood portrays this ?All-night-long-continuous-non-stop-sex?, that I know can be real, without stopping all night. But how long does sex usually last, on average. Assuming neither of the two are having any problems coming early, or not coming at all?

2. Is it harder for a guy to come when he's on bottom, and the girl is on top?

3. I just started birth control pills, I?m in the middle of my second week of it. And I had a bit of spotting yesterday. Even when I wasn?t on the pill, I didn?t usually have spotting in between periods, and I would still be two weeks from starting my period. Is this normal?

Thank you for answering.

Please stop mass-posting this in different stickies. As I posted in the other sticky you posted in, YES IT CAN GET A GIRL PREGNANT. Pre-c** has sperm in it, thus it can get you knocked up.

Pulling out and withdrawl is useless, and you're asking to get pregnant if you continue to use that method. Use a condom every single time, or don't have sex at all. Sex isn't for children who try to pretend they're older and ready for sex. Be responsible and mature about it, because if anything happens there WILL be consequences you'll have to deal with, or don't have sex at all.
