Cock banjo string... snap!

Okay, I'm sure that the subject title summarises this pretty well. I was just fucking with this girl, who with both of us having been drinking a little, just dove straight into sex. Well she wasn't too wet yet, but that wouldn't stop me... so I just made a *little* more effort and suddenly "ouch". Bit between head and skin...*snap*. Well I didn't say anything as I knew she was on her period and she wanted to drink my cum, but now (like not even ten minutes after) I'm in my room and it slowly keeps on bleeding.
WHAT HAPPENS NOW??? Can I have sex straight away (in the shower... she wants to in about 40-60 mins..) or is there something really bad about this (doctor type thing?)
