Why does the tip of my hurt after i go to the bathroom after masturbating?

i masturbated a few days ago and i remember i didn't really *** it was like clear kinda i went into my bathroom and took a piss and i shuck my around getting it out of my underwear and right before the piss came out i got a bit of semen in the toilet the *** was at the surface of the water and was very visible i slouched down to get a better look at it. it looked like *** so i was like ok i guess i didn't *** and that was all i was gonna ****. i flushed and walked out of the room and i felt a kind of stinging feeling right on the tip of my at the urethra. i forgot to mention i am not completely circised the doctor messed up a bit i think he was drinking. does that have anything to do with the stinging it went away but im confused.. im only 14 can i have a doctor to answer?
