Ob-Gyn questions? Ask a gynecologist online.
first of all I would recommend a comprehensive laboratory examination of urine from you and your partner to exclude a permanent re-infection. The result then facilitates a specific treatment. It´s important too, to empty your bladder immediately after every sexual contact, this can prevent infections.
I hope your problem will be resolved soon, best regards,
