Syphilis- Syphilis is causes by a bacterium, not a virus. The germ enters the system through the breaks in the surfaces of sex organs. There are four main stages of syphilis: Primary, secondary, latent and late stages. During the primary stage a small painless sore called a chancre appears at the site of where the infection entered the body. This sore usually goes away within a week. The secondary stage is characterized by sores that can appear in the mouth, flu like symptoms and a non-itchy rash all over the body. In the latent stages the symptoms disappear for years while attacking and damaging internal organs of the body, including the brain. In the late stage blindness, deafness, heart disease and death occur. If an antibiotic is taken during the first 3 stages it can be cured. 

Chlamydia- Chlamydia is the most common bacterial STD in the Untied States. It can occur at the same time as Gonorrhea. Within 3 weeks of becoming infected symptoms include painful urination, vaginal or penile discharge, abdominal pain and urethral itching. About half of men and 90% of women are asymptomatic, meaning there are no outward signs and symptoms. In this case only a blood test can verify if somebody has Chlamydia. In females, Chlamydia is the leading cause of pelvic inflammatory disease (PID), which may result in sterility or ectopic pregnancy. Chlamydia can be cured with antibiotics. 

Gonorrhea- Gonorrhea is one of the most common bacterial sexually transmitted diseases. In males the most common point of infection is the tip of the penis. Males usually know when they are infected by a pus like discharge and /or burning sensation when urinating 3-8 days after becoming infected. In females infection usually starts in the cervix, and some females may experience a vaginal discharge. Over half of women infected will be asymptomatic and experience no symptoms at all. If left untreated this can cause sterility in females. Antibiotics can treat Gonorrhea. 

Pubic Lice- Pubic Lice is also known as crabs or crab lice. This is caused by a parasite that feeds on tiny blood vessels in the pubic region. These tiny lice infest hair around the genital. They are very contagious and can be transmitted from person to person from sexual intercourse, shared toweling shared clothing or shared bedding. It causes intense itching and may be accompanied by a rash. Blood spots may be found on the underwear. They pubic lice can be killed by an Over the Counter (OTC) medical shampoo such as RID or NIX 

Genital herpes is a sexually transmitted disease (STD) caused by the herpes simplex viruses type 1 (HSV-1) or type 2 (HSV-2). Most genital herpes is caused by HSV-2. Most individuals have no or only minimal signs or symptoms from HSV-1 or HSV-2 infection. When signs do occur, they typically appear as one or more blisters on or around the genitals or rectum. The blisters break, leaving tender ulcers (sores) that may take two to four weeks to heal the first time they occur.  Although the infection can stay in the body indefinitely, the number of outbreaks tends to decrease over a period of years. HSV-1 and HSV-2 can be found in and released from the sores that the viruses cause, but they also are released between outbreaks from skin that does not appear to have a sore. Generally, a person can only get HSV-2 infection during sexual contact with someone who has a genital HSV-2 infection. Transmission can occur from an infected partner who does not have a visible sore and may not know that he or she is infected.   There is no treatment that can cure herpes.  The surest way to avoid transmission of sexually transmitted diseases, including genital herpes, is to abstain from sexual contact, or to be in a long-term mutually monogamous relationship with a partner who has been tested and is known to be uninfected. 

HPV- Genital human papillomavirus (HPV) is the most common sexually transmitted disease (STD) and there is no cure. It can cause Genital warts which usually appear as small bumps or groups of bumps, usually in the genital area. They can be raised or flat, single or multiple, small or large, and sometimes cauliflower shaped. They can appear on the vulva, in or around the vagina or anus, on the cervix, and on the penis, scrotum, groin, or thigh. Warts may appear within weeks or months after sexual contact with an infected person and has been linked to Cervical cancer. For this reason, it is important for women to get screened regularly for cervical cancer.  Genital HPV is passed on through genital contact, most often during vaginal and anal sex. A person can have HPV even if years have passed since he or she had sex. Most infected persons do not realize they are infected or that they are passing the virus to a sex partner. 

NGU- Nongonococcal Urethritis is a bacterial infection transmitted through the urethra in males and cervix in females. Varying bacteria that somebody may come into contact with is the cause. The specific cause of NGU has not been discovered yet, but despite this, NGU can be diagnosed and treated by a doctor and is usually cured with antibiotics. Symtoms are usually more noticeable in males and signs may include a discharge from the penis and a mild burning feeling during urination for 1 to 3 weeks after infection. Females may have vaginal discharge or pain in the lower abdomen
