I'm sorry to hear you have an STI that keeps coming back. That must be really frustrating. Here are some suggestions that may help:

 - Make sure you and your partner(s) get fully treated. If you have antibiotics, make sure you finish the full course. Some STIs can cause reinfection if not properly treated. 

- Take a break from sex until you and your partner(s) have both been treated and tested negative.

- Use protection like condoms every time you have sex. This can help prevent reinfection.

- Avoid things that could irritate the affected area, like scented soaps, sprays, etc. Stick to gentle, fragrance-free products.

- Practice good hygiene - wash your hands before and after touching the affected area.

- Wear loose, breathable clothing and cotton underwear. This can help avoid irritation.

- Try not to stress. Take care of yourself. Your health is what matters most!

- If symptoms persist, go back to the clinic. ? You may need a different antibiotic or a longer course of treatment. ?

 I hope you feel better soon!
