Sexually transmitted diseases or STDs are infections that can be transferred from one person to another through sexual contact. Sexually transmitted infections have probably been around for thousands of years. It is important to realize that sexual contact includes more than just sexual intercourse (vaginal and anal). Sexual contact includes kissing, oral-genital contact, and the use of sexual "toys," such as vibrators.

Most STDs are treatable. However STDs, such as herpes, AIDS, and genital warts (all of which are caused by viruses), have no cure. Therefore, a public awareness and education about these infections and the methods of preventing them is important.

There really is no such thing as "safe" sex. The only truly safe sex is abstinence. Sex in the context of a monogamous relationship wherein neither party is infected with a STD is also considered "safe". Most people think that kissing is a safe activity. Unfortunately, syphilis, herpes, and other infections can be contracted through this relatively simple and apparently harmless act. All other forms of sexual contact carry some risk. Condoms are commonly thought to protect against STDs. Condoms are useful in decreasing spread of certain infections, but they do not fully protect against other infections such as genital herpes and genital warts.
