Suggest Medication For A Wound On The Penis Caused By Biting

My girlfriend bit my penis & it bled a little throughout the day it had stopped but when we had sex & i ejaculated on her blood was mixed in it a little & but no blood ever really came out as though it was really bleeding. This morning i check it & it s no longer bleeding. It doesn t hurt or anything. She keeps telling me maybe i should go to the doctors but I d rather not for insurance reasons. What do you think ? Is everything okay ? Will it heal back up on it s own with no problems ?
