i am 17. i am a male. i am 6'3", and i weigh about 183 lbs. about a week ago i received oral sex, but did not perform it. it was my partners first time and they have no symptoms of anything. 3 days later the tip of my urethra began to feel irritated, and burn when i had to urinate. the next day i noticed a light mucus like discharge. just yesterday the discharge discontinued but there is still a slight burning sensation. ive never had sex before other than receiving oral from this partner before. what is the problem?
