HIV is a virus that destroys the immune system and thus weakens the body's ability to fight disease and infection, even common infections like flus and colds. HIV usually progresses to AIDS. This makes HIV the most dangerous sexually transmitted infection today. It is the fifth leading cause of death for the young under 40 in the United States. At this time, no one has been cured of HIV or AIDS.
There are certain physical, hormonal and psychological mechanics that come into play when it comes to human sexual response, and understanding those is essential to lay the foundation for understanding how sex works for ourselves and for our partners. Once we understand how our bodies work when it comes to sexual response, we've won half the battle of learning how to enjoy that and incorporate it as a healthy part of our lives, both alone and with others.
If you have NOT gladly and freely consented to and participated in sexual activity -- if you have not in some way said a big yes and wanted to keep saying a big yes -- and someone else had sex with you anyway, that is rape. No matter what ANYONE tells you, it is not your fault. There certainly is fault, but it lies with the rapist, not the victim.
