If you have had unprotected sex and you experience any of the following symptoms you must ensure you are checked out.

  • Pain or discomfort when urinating
  • Unusual discharge from the vagina or penis
  • Inflammation or discomfort of the genital area
  • Rectal pain, bleeding or discomfort
  • Bleeding during or after sex (female)
  • An unusual sore throat (if oral sex has been undertaken)

It must also be remembered than some STIs can be asymptomatic, meaning you may not present any symptoms.

The key thing to remember; if you have had unprotected sex it is possible that you have an STI.


One of the most common STIs that is generally asymptomatic, Chlamydia can cause infertility in both men and women, and therefore quick treatment is essential.

Another very common STI, second to Chlamydia, genital warts caused human papilloma virus (HPV).

The infection presents itself as small fleshy bumps that are not necessarily passed by sexual contact; they can be passed skin to skin.

The warts are not necessarily painful but can look unpleasant and be a nuisance as they have a tendency to re-occur.

It should be remembered that warts can appear some time after being exposed to HPV and therefore it should not be assumed that your partner has been unfaithful if they suddenly have genital warts.

They could have contracted the infection months or even years ago.
