Small spots on penis

I have randomly started getting small spots on my penis and sores. ive been to the sexual health clinic and they can only test for open sores and have done the normal checks which have come back normal. its mission impossible to get an appointment at my GP these days, so i was wondering if anyone could help also i have clear/ cloudy discharge from the urethra

And you say the clinic done the full set of sti tests.. Looking at those spots and the discharge it’s looks like an infection
