Tracing a sexual history

A 20-year-old woman attends her GP with a sports injury to her ankle. She is offered and accepts a routine screening test for chlamydia. 

The test returns positive and an appointment is arranged. The GP explains that she will need treatment and that anyone that she has had sex with in the past six months should be offered treatment as well.

On further history, the GP discovers the woman has been with her regular male partner for the past two years. The GP explains that he will need treating and testing. 

The GP asks if she has had any other sexual contacts in the past six months.
