About SEX

Sex refers to the male and female duality of biology and reproduction. Unlike organisms that only have the ability to reproduce asexually, sexed male and female pairs have the ability to produce offspring through meiosis and fertilization. The two sexes attract one another and communicate their readiness to procreate through differences in their biology.An organism's sex category reflects its biological reproductive function rather than its sexuality or other behavior. The female sex is defined as the one which produces the larger gamete and which typically bears the offspring. In contrast, the male sex has a smaller gamete and rarely bears offspring. In some animals, sex may be assigned to specific structures rather than the entire organism. Earthworms, for example, are normally hermaphrodites.

My Favorite Book

This book demonstrates that the principles of ancient Taoist texts are applicable to stimulating and improving sexual health today.(by Jolan Chang)

What are the first symptoms of HIV infection?

The only way to know for sure whether you are infected with HIV is to have an HIV antibody test.
The symptoms of initial HIV infection are not very specific. If a person is infected, a few weeks after infection some people experience a flu-like illness. Only a fifth of people experience symptoms which are serious enough to require a doctor's attention.
Several years after infection a person may experience symptoms of particular illnesses and cancers. These are the result of the infected person's immune system being damaged by HIV to the point where it is no longer able to fight off these opportunistic infections.
In each case, HIV infection is difficult to diagnose with out having taken an HIV antibody test first.
