I expect it is more the erections perhaps stretching the urethra at the point it was reconnected. It was over three months (for me) before the dots of blood and scar tissue stopped.
The Cialis is to improve blood flow into the spongey tissue in the penis. I'm not aware of any blood-thinning characteristic, or any side effect that causes bleeding. Are you trying to generate erections? If so, perhaps you should slow down on that.
But as always, call the uro, and insist on an appoinment.
