STI stands for sexually transmitted infection, also known as sexually transmitted diseases STD.
Sexual intercourse, oral sex and anal sex are all ways to contract an STI. Contact with bodily fluids such as saliva, blood, sperm and vaginal discharge can also lead to an infection. But a few, can be transmitted through skin contact alone. Some will show little or no symptoms.
Symptoms you should look out for:
Pain when passing urine, or the need to pass urine more frequently
Unusual discharge from penis, vagina or anus.
Any of the following around the genital or anus areas, rashes, warts, sores, blisters, excessive itching.
Pain during intercourse.
Women, bleeding between periods or after sex.
Not all sexually transmitted infections can be cured. However most can be treated and controlled if caught and diagnosed in time.
If you believe you have contracted an STI it is most important to refrain from sexual contact, inform any relevant sexual partners and
