• What is sex ?

Sex is a sign of gender identity and it is decided by the nature. when you were born then Doctor probably assigned your sex- as Male or Female based on your sex anatomy.

 But it doesn't mean about your gender identity. In some of theu people assigned sex and gender identity are same or in line with each other and these people are called Transgender. For an example, a person could be born with penis but identifies as female.
It is commonly divided into two categories  
                                                                 


                   &

• Sex organs or reproductive organ and sexual activity :-

  A sex organ (or reproductive organ) is any part of an animal's body that is involved in sexual reproduction. There are two sex organs in all  Male and females.
Internal sex organs also called as primary sex organ and external sex organ are also known as secondary sex organ.

   The reproductive organs together constitute the reproductive system. 

• Primary sex organs in animals
• Male sex organ is  testis,
• Female sex organ is ovaries.

• The external sex organs – The genitals or genitalia, visible at birth in both sexes, and the internal sex organs are called the secondary sex organs.

Mosses, ferns, and some similar plants have gametangia for repuroductive organs, which are part of the gametophyte.

 The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule. Coniferous plants likewise produce their sexually reproductive structures within the gametophytes contained within the cones and pollen. The cones and pollen are not themselves sexual organs.

Sexual and Reproductive Anatomy

labia majora (outer lips) and labia minora (inner lips). libia majora are usually fleshy and covered with pubic hair . 

labia minora are inside the labia majora it begin at clitoris and end under the oprning to vagina.

labia can  be short or long wrinkeled or smooth. Often one lip is longer than the other. 

They also vary in color from pink to brownish black.The color of labia can be changed with age degradation. Some have larger outer lips than inner lips, and many have larger innner lips than outer lips . Both are sensative ,and swell when turned on.

• Clitoris

The tip of the clotiris is located at the tip of vulva. 
Everyone's clitoris is a differ in size. It can be about a small pea or as big as a thumb. The tip of the Clitoris is covered by clitoral hoop.

The beginning of the clitoris through inside body, back, and down sides of the vagina. This part is called shaft and cura (root and legs), and it is about 5 inches long.

• Cervix

Cervix divides vagina nad uterus, located right between the two. It looks like a donut with a tiny hole in the middle. Its role is to connect uterus and vagina. It lets menstrual blood out and sperm in. Cervix stretches open (dilates) during childbirth.

One can feel cervix at the end of vagina when inserted fingers, or panis into vagina. Cervix Separates vagina from rest of the body.

• Uterus

The uterus is a pear shaped muscular organ about the size of fist. Its sometimes called  womb because here a fetus grows during pregnacy. During sexual arousal, lower part of uterus lifts towards belly button. That's why vagina gets longer when its turned on and it is called "tenting".

• Fallopian Tubes

The fallopian tubes are a pair of narrow tubes which carry eggs from ovaries to uterus. Sperm travels through them to try to fertilizes egg.

• Fimbriae

The fimbriae look likes tiny fingures at the end of  each fallopian tubes when ovary releases an egg, they sweep it into fallopian tube.

• Ovaries

Ovaries store eggs. They also produce hormones, including estrogen, progesterone, and testosterone. These hormones controls things like period and pregnancy.

During puberty, ovaries start to releases an egg each month. They do so intill menopause.

• Bartholin;s glands

the bartholin;s gland present near vaginal opening. They releases fluid that lubricate;s vagina to make it wet when vagina turned on

• Skene's gland

the skene's glands are on either side of urethral opening. They releases fluid during female ejaculation. They are also called paraurethral  gland or female prostrate gland.

• Hymen

the Hymen is the thin, fleshy tissue that streatches across part of the vagina. Hymen vary a lot in how much the vaginal opening they cover and they can sometimes tear and cause bleeding .

The average size of adult eract penis 5-7 inches long. The size of penis when it's flaccid dosent have much to do with its size when its hard. Some penis get nuch bigger when get hard.

Penis with foreskin are called uncircumcised as there is no any cut on forskin, and the penis having cut on forskin are called circumsied penis.

the panis having diffent shape and sizes but all penis  have the same parts as :

• Glans

Glans id the head or tip of the penis. The opening of urethra is here. This is where pre-ejaculate and semen comes out of and its where you pee out of. It's very sensitive part of penis..

• Frenulum

The frenulum is where foreskin meets the underside of penis. It looks like a small V just below the head. Usually part of it remains after circumcision. It is very much sensative.

• Scrotum

The scrotum is the sac of skin that hangs below penis. Scrotum holds testicles and keeps them at the right temperature If it's too cold ,scrotum pulls testicles closer to the body. ?If it's too warm testicles hang away from body.

The epididymis is a tube where sperm matures. It connects each testicle to each vas deferens, and it holds sperm before 

• Vas Deferens

It is a narrow tube that carries sperm from the epididymis to the seminal vesicles during ejaculation. There are 2 of them one connected to each epididymis.

• Seminal Vesicles

Seminal vesicles are 2 small organs that produce semen, The fluid that aperm move around in. They are located below the bladder.

• Prostate Gland

The prostate gland makes a fluid that helps semen move. Its about the size of walnut or golf ball. The prostate gland is sensitive to pressure or touch in a way people find pleasurable.

• Cowper's gland

The Cowper's glands produce a fluid called per-ejaculate or precursor. The fluid prepares urethra for ejaculation. It reduces function so semen can move easily .The Cowper's gland are under prostate and attach to urethra. They are also called Urethral gland.

• Urethra

It is a tube that carries urine , pre-ejaculate, and semen to urethral opening and out of body..
