Itching at top of Urethra (and on head?)

[RedXIII]

I am a 25 year old male that is normally very safe about sex and have not had many partners at all, but had unprotected sex one time about a month ago... since then every once in a while (more likely after masturbation) it seems that I have felt a slight itching at the top of my urethra to maybe max an inch down inside... i also feel as if there is an itchiness when i masturbate if any semen gets in my foreskin (I'm uncircumcised), almost like the semen itself makes me itchy

I have not seen a rash or anything

I have no had any discharge or anything else that would lead me to believe it is syphilis or gonorrhea (done some research)... and the girl also said she has been tested for STDs and everything came back ok... I also have never had any STDs

what could be the reason for this happening?

Not really sure, it might be a bacterial infection or yeast infection manybe. Best advice is to see a Dr.

of note, I also have probably been masturbating more than usual over the last month... could this be related? ive heard it can irritate the urethra and can this feeling...

It could be, but only a Dr would be able to tell you.
