Overview

An STI (sexually transmitted infection) is an infection passed through sexual contact. You can find out if you have an STI by doing a test.

Genital warts

Genital warts are small, soft lumps that appear on the genital or anal area. They are caused by human papillomavirus (HPV), and you usually get them through skin-to-skin contact during sexual activity.
