How is it possible that my penis bents to the right when I have an erection after my circumsision? I had a surgery 6 weeks ago. By swelling maybe?

Surgery not reason. Maybe you had that before , there is a condition called peyronie's disease is where the penis is deviated to one side but if there is not pain esp on intercourse it is not serious but there is medication that helps sometimes and surgery for peyronies only if intercourse is a problem.
