What Are The Symptoms Of Penis Fracture?

I m a little worried I may have fractured my penis. I was masturbating Saturday night. I had ejaculated and my erection was going away. As I went to pull up my pants my semi-flaccid penis caught on my waistband and was summarily bent quite a bit. I heard an audible popping sound, though there was no pain. I immediately began searching the Internet for symptoms and solutions as I was very worried about the popping sound. There has been no bruising or discoloration and there has been no pain or malformation. I ve had erections in the two days since then, though none of them have been as firm as it normally is. From what I ve read the fact that I ve had erections since the incident and the lack of pain, bruising, and malformation has encouraged me to believe that I had not fractured it but only minorly injured myself. However, the lack of the usual firmness still has me worried. What are some recommendations you may have?
