Ever thought of skipping a visit to your medical store to grab a packet of condoms because you thought it wasn’t necessary since all you were going to do was have oral sex? Well, that oral sex does not require protection against STDs is an assumption that only an ignorant would fall prey to. It is popularly assumed that sexually transmitted diseases occur due to unprotected vaginal or anal sex, but unprotected oral sex may also lead to contraction of STDs. Here are some common STDs caused by unprotected sex.


Genital Herpes

Herpes simplex virus (HSV) causes genital herpes, which is a common sexually transmitted disease. Genital herpes is further divided into types, namely HSV1 and HSV2. HSV1, also referred to as cold sores, is found around the lips and mouth and HSV2 is associated with the genital area and anus.  A common infectious diseaseamong Australians,  people contract genital herpes through skin-to-skin contact and remains untreatable even today. Women are twice more susceptible to herpes than men. An individual can be diagnosed with HSV1 and HSV2 at the same time. Genital herpes presents the following symptoms.

  • itching and tingling
  • blisters that become ulcers in a few days
  • swollen and tender glands in the groin


Please note that the symptoms of genital herpes remain inactive for a considerable time and therefore, will go unnoticed and get transferred to sexual partners.

Chlamydia Trachomatis

It is another common bacterial STD, which can affect both the sexes. In women, chlamydia leads to infection of the cervix and in men, that of the urethra.  Vaginal and anal sex can lead to transmission of bacteria causing Chlamydia.  Chlamydia is treated using antibiotics, such as azithromycin or doxycyline. Condoms can prevent the transmission of Chlamydia. Listed below are the symptoms presented by Chlamydia in men and women.


  • Inflammation of the testicles.
  • Transparent discharge from the penis.
  • Burning sensation while passing urine.
  • Reddened opening of the penis.


  • Irregular vaginal bleeding, especially after sex.
  • Changed colour and smell of vaginal discharge.

Human immunodeficiency virus is commonly known as HIV. HIV causes Acquired Immunodeficiency Syndrome (AIDS), which is a deadly sexually transmitted disease. HIV adversely affects one’s immune system and leads to its complete damage eventually. The symptoms caused by HIV/AIDS often mimic signs of other illnesses and therefore, are often misdiagnosed. The only sure way to diagnose transmission of HIV is to go through the HIV test. Some of the common symptoms of HIV include:

  • weak immune
  • fatigue, fever and headache
  • sore throat
  • swollen lymph glands
  • skin problems, such as seborrheic dermatitis.
