Was doing deep throat oral sex with partner, and after that partner was stimulating using hands... when suddenly i noticed blood started to come out from urethra. Washed with tap water, squeezed a few times, and blood was still coming with each squeez. Pee-ed so as to clear the blood. Felt a bit of irritation while Urinating, but that was not at all uncomfortable. Cleaned with diluted dettol. How to go about check up, if any. First such case. Full body checkup reports 2 months ago were all fine.
