Please help me with this

My symptoms started 3 months back . Burning after urination and pain in the perineum etc. i met the dr he asked me to take a semen culture which i did and came positive for klebsiella . I took 3 weeks of antibiotics and i felt wayyy better and immediately after completing the course i got same symptoms again and dr asked me to take the same antibiotic for another 3 weeks my symptoms slowly reduced.

Currently i have mildd symptoms like some itching and discomfort in rectum and milddd urinary hesitancy but nothing much .

I gave a culture again and this time it showed scanty growth of e coli. And previous antibiotics have become resistant. Should i be worried ?
