The short answer
If only one partner is treated, the infection passes straight back at the next sexual contact, often called 'ping-pong' infection. For trichomoniasis, chlamydia and gonorrhea, partners must be tested and treated at the same time, and both should avoid sex until treatment is finished.
Many men carry trichomonas, chlamydia or gonorrhea without symptoms. You can be cured and then quickly re-infected by an untreated partner.
