STIs & safer sex

General information about STIs

Sexually transmitted infections (STIs) can be viral (like HIV) or bacterial (like Chlamydia). Some are transmitted through body fluids such as semen or blood and some are passed on simply by skin to skin contact.  If you have unprotected sex (that's sex without a condom or a dam) you can be at risk of catching an STI.  Some other common examples of STIs are Gonorrhoea, Syphilis, Herpes and Genital Warts. 

STIs are more common than most people believe. It's estimated that 1 in 10 sexually active people under the age of 25 have Chlamydia. HIV infection has not gone away; in fact more people are being diagnosed with it every year. There are now treatments but still no cure for HIV; your quality of life is seriously impaired by both the treatment side effects and the infection itself.

You are most at risk of STIs including HIV if you have unprotected penetrative vaginal or anal sex. Oral sex is also a risk.


Safer sex

Safer sex is a term used to describe sex with fewer risks or where you take steps to protect yourself.  Safer sex can mean taking part in sexual activity other than intercourse, such as kissing and fondling, and protecting yourself from STIs by always using condoms. If you have safer sex you are far less likely to pick up an STI, including HIV. For more on protecting yourself with condoms and dams see the section on condoms, dams and lube
