Anatomy & development

Sexuality is about appreciating the sexual anatomy & development of both genders.

Why women cannot orgasm through intercourse

Orgasm is vital for men, so it is assumed to be equally vital for women. (1) A woman is impregnated regardless of orgasm Male orgasm triggers ejaculation, which is vital for reproduction. A woman cannot ejaculate because she lacks the male glands. Since ovulation occurs automatically, there is no reason for a woman to orgasm…

How we know that the vagina is not a sex organ

If women had orgasms from inserting objects (such as an erect penis) into the vagina they would seek this kind of stimulation themselves. Research clearly identified the clitoris as the focus for female masturbation. The hymen is a small flap of skin that covers the entrance to the vagina (in most women). When the hymen…

The internal anatomy involved in reproduction

Every foetus starts out with the building blocks for both male and female reproductive organs. All embryos (regardless of sex) have Wolffian ducts and Müllerian ducts. These two sets of embryonic ducts determine our ultimate internal reproductive anatomy and consequently our sex. Development of our internal reproductive anatomy depends on hormones produced by the testes…

Men can easily orgasm by penetrating the mouth, vagina or anus. For a man, the sight of his erect penis penetrating an orifice is perhaps the greatest…

The female erectile sex organ (or phallus)

In the absence of testosterone, the genital tubercle forms the female phallus, called the clitoris. The clitoris is made up of the glans, the shaft and the internal organ. Women do not have the anatomy or the mental response to make arousal easy, so orgasm is an occasional female pleasure. A woman’s sex organ (clitoris)…

The male erectile sex organ (or phallus)

A man’s sex organ (penis) is separate from his internal reproductive anatomy (testes and glands). The penis is made up of the glans, the shaft and the internal organ. The penis has three main functions. Firstly men use their penis to urinate (but only when flaccid). The urethra is a tube that runs down the…

Human sexual anatomy and development

Sexuality is about appreciating the human body and sexual anatomy. We need to understand the function of the male and female genitalia as well as the changes that occur throughout our lives. It is also useful to be aware of the stimulation that may be pleasurable or lead to orgasm. By combining gene pools from…
