Will wearing a condom and having intercourse after Mycoplasma clears lead to a recurrence?

Patient's question:

I had a missed miscarriage in May this year. Then in August, a follow-up test showed positive for mycoplasma. I took azithromycin for the first time, and then took norfloxacin and co-trimoxazole. By the third time, I finally tested negative. During this period, my boyfriend also tested positive, but he later tested negative after treatment. I want to ask the doctor what precautions to take after becoming negative, and whether a follow-up test being negative after finishing the medication (2 weeks after stopping) means it's cured? Do I need to go to the hospital again after a certain period to check if the mycoplasma has recurred? Will having sex with a condom after becoming negative cause a recurrence? I heard that having sex will always lead to recurrence—is that true? Drinking (baijiu) will also

Doctor's answer:

After the mycoplasma test turns negative, have unprotected sex once, and you won't get infected again. However, the prerequisite is that the other person is healthy and does not have mycoplasma infection. Four days after having sex, if the previous test was already negative, this test will also be negative.
