Wearing a condom during HIV coitus reduces the chances of contracting HIV, but it does not guarantee that you will not get HIV. Sexual contact is an important way of spreading HIV, including unsafe homosexual and heterosexual contact. When the blood, semen and vaginal secretions of a person infected with HIV enter the bloodstream of another person, they may transmit HIV to the other person. Wearing a condom can go a long way toward preventing infection from occurring when the virus enters the bloodstream through a break in the mucous membrane of the anus or sex organ. Not a single unprotected sexual contact is necessarily infected, there are certain possibilities,, condoms after damage, accidental dislodgement and mucous membrane rupture are factors that lead to the transmission of AIDS. Therefore, in order to prevent AIDS, one should avoid any unprotected sex with others.
