You need to see your doctor, and do it soon. Even if you are in a really high covid area like California or Florida, you need to be seen.
It sounds as if you have a prostate infection. It can be caused by an STD, but might not be. It could be a urinary tract infection that's spreading. Unfortunately, you took antibiotics, which may interfere with testing for STDs, but you need to go to the doctor anyway.
Blood in your urine always indicates an urgent need to see a doctor. That, the pain at the tip of your penis and the urine spray all indicate a prostate infection or inflammation.
Get checked by your regular doctor and ask for a referral to a urologist. A urologist isn't going to be inundated by covid.
Don't wait on this. A UTI or STD that goes untreated can cause serious problems.
Please let us know how you're doing.
