Androgens play a part in erection and response of the penis, the clitoris and the vagina. For those with a vagina, estrogens influence vaginal lubrication and elasticity of vulvovaginal tissues.
When the penis is not erect, it tightens to narrow the foreskin opening. During erection, the ridged band forms ridges that go all the way around, about halfway down the shaft. The reddish or purplish glans or glans penis (head of the penis) is smooth, shiny, moist and extremely sensitive.
The vaginal canal ranges from roughly 1.5-3.7 inches long, but it stretches during sex to accommodate a penis. Most vaginas can accommodate an average erect penis, which is around five inches long.
The vagina becomes lubricated, or slippery, by the passage of fluids through the vaginal walls. The man will usually insert his penis into the woman's vagina after the above processes have begun. (It is difficult, although not impossible, to insert a flaccid penis into a vagina. Similarly, vaginal lubrication makes the process much easier.)
In reproductive sexual intercourse between a male and female, the erect penis is inserted into the vagina and moved in and out. The vagina places pressure on the penis, which can cause the male to have an orgasm and ejaculate into the vagina, causing insemination (meaning that semen enters the female's reproductive system.)
PenetrationPenetration refers to the insertion of a penis or other object into an orifice such as a mouth, vagina, or anus. Penetration is an element of sexual pleasure and reproduction as well as a symbolic action defining virginity, marriage, and sodomy.

The penis becomes erect due to increased blood flow, allowing for penetration. As sexual arousal intensifies, the male may reach orgasm and ejaculate semen [1]. Female Response During Coitus Females also undergo physiological changes during coitus, such as increased heart rate, blood pressure, and lubrication of the vagina.

In the penis, this [10] tissue engorges with blood during sexual arousal and becomes compressed against the unyielding tunica, creating penile rigidity - a true erection. The lack of this plexus in the clitoris indicates that while the organ can become tumescent or engorged, it cannot, like the penis, become stiffly erect.
When a woman becomes aroused, the vaginal lips and clitoris swell, the nipples on her breast become erect, and the vaginal walls fill with blood. The vagina becomes lubricated, or slippery, by the passage of fluids through the vaginal walls. The man will usually insert his penis into the woman's vagina after the above processes have begun.

Both the clitoris and the penis have some anatomical and physiological differences. During penile erection [3], sexual arousal triggers the relaxation of smooth muscles and the dilation of blood vessels in the penis. This increased blood flow fills the spongy erectile tissue within the penis, causing it to become erect and firm.

Coitus is sex between a man and a woman, with penetration of the erect penis into the vagina. The repetitive movements of the penis and of the vagina generally end in an orgasm and the expulsion of the sperm (ejaculation) into the vagina. Coitus may also lead to the fertilization of an ovum by a sperm cell and the conception of a child. ÂInternational 1016_04_49332
When erect, the stiffness of the organ allows it to penetrate into the vagina and deposit semen into the female reproductive tract. The shaft of the penis surrounds the urethra (Figure 22 4 1). The shaft is composed of three column-like chambers of erectile tissue that span the length of the shaft.

Penetration: Once the penis is erect, it can enter the female vagina during intercourse, allowing for the transfer of sperm. The stiffness and length provided by the corpora cavernosa help facilitate effective penetration.
The Penis The penis is flaccid for non-sexual actions, such as urination, and turgid and erect during sexual arousal. The shaft of the penis surrounds the urethra (Figure 27.1.5). The shaft is composed of three column-like chambers of erectile tissue that span the length of the shaft.
