Talk to Urologist on Blisters On Penis

Last night had sex with my wife, A while unprotected then protected. I felt pain a bit in my penis during unprotected sex. After sex i washed and every thing was fine. Today when i wake up i had many small blisters on my penis. I read a bit regarding that and it seems they are caused by frictions and rough sex and can go away on their own after some time. Kindly check and confirm its nothing serious. Allhamdullilah me and my wife are perfectly fine and do not have any kind of disease.
