hi there, i had sex 2 months back and and while we were doing oral i felt a sting and i saw blood coming out of my penis. later i got to know that it was my frenulum which got ripped. i gave it 3 weeks to heal . after that it went normal but last week while having sex the second time, i felt a lil similar thing but it wasnt that painful as it was before. blood came out but it wasnt hurting. now its healed and what ive noticed is that my frenulum is the thing which is being ripped n going back. can u tell me if its normal or not?
