Scrotal bruising, should I be concerned?

[jjohnson21]

A couple days ago, I was having sex with my girlfriend and at one point Icame out and hit her pelvic bone. I did not notice any popping sound or felt any pain but I did start to lose my erection slightly. We took a moment and I was able to get back my erection but when I tried to get back inside her, I felt a dull pain at the slighty deeper in the base of my penis where the scrotum connects. We decided to stop and the next morning, I noticed I had what appeared to be a blue/purple bruise that starts at the lowest portion of my shaft where the scrotum connects and down the center of the scrotum and continues on past the scrotum towards my anus. There is swelling where the bruise is, in addition to a small lump that I have not noticed before in my scrotum (Obviously I am not an expert and hope it is just a small hematoma). I have only experienced some dull pain, like it is sore, deeper in my scrotum. I have no troubles urinating and I can obtain an erection. My testicles feel normal and with no pain. I have been icing occasionally. I am a college student and away from home so I would like to avoid an urgent care visit but will if it is necessary. Should I be concerned about a penile fracture/anything else or will this most likely clear up on its own? What else should I look out for i.e. in case of infection? What can I do besides ice and wait? Thank you
