As such there can be many infectious and non infectious causes of anal discharge you describe.Since your
doctor has already prescribed antibiotics without much result i do think that that possible cause of discharge is non infectious.
Possible non infectious causes may include
Irritable bowel syndrome
I do think that you should be further investigated.
Further test that may be useful include ano-rectal examination,proctoscopy,colonoscopy etc.
Also ultrasound of whole abdomen and testicles can be useful to rule out any pathology.
I hope this helps
