Cystitis Relief

Please excuse my poor spelling of medical terms.
I have the following symptoms, and im sorry if i become graphic at times.
-Itch/burn trough the urethra when touched
-Burning sensation when urinating
-SOMETIMES a whiteish sticky pus-like fluid from the opening of the penis.

Im thinking that MAYBE the fluid could just be pre-come or come for some odd reason (though i havnt been getting aroused) and the pain and irritation could be a UTI (though those are supposedly rare in younger males)

I am 18 years old. Please help.

the former.

if it is sticky, it is more of gonorrhea. if it is more watery, then it is chlamydia.

Just got done taking antibiotics for a UTI/kidney infection, why is there still discomfort?
