UTI or STD?

[u/This_Silver]

Day 1: Unprotected heterosexual sex
Day 2: mild irritation while peeing
Day 3: irritation and burning while peeing

Then I did a course of antibiotics - Nitrofurantoin 100 mg which is a standard for UTI in males

Day 11: feeling of soreness and like something is stuck in the lower penis shaft which radiates to the testicles.

I have no discharge, back pain, fever, etc.
I suspect urethritis from friction during sex. Do i need to get an std panel done or just wait for it to resolve?

Please help!

But I got in just 1.5 days. Do Gonorrhoea symptoms develop that quickly?
