Bitten penis - Blood in urine

Wondering how serious this is: while begining to "have relations" with my gf last night she got a little over aggressive and bit on it harder than she realized. This morning when I got up and used the bathroom the first thing to come out was a little blood, then again today the same thing when I used the bathroom. It feels like there is a scratch on the bottom of my penis but nothing on the outside of the penis to indicate trauma. Does not hurt to urinate. Will this just heal it self or is this something I should seek medical attention for?

If there is no break in the skin externaly it is possibe that there is some minor damage to the urethra. I have had damage to the urethra after a cystoscopy and some blood in the urine was noted for several days after the procedure. On all occasions it cleared up on it's own.

All the best.
