Cut myself down there..

I was just shaving and cut myself.. Just a little bit bigger than what I would consider a knick. I know this is TMI but in case it helps get me tips on how to take care of it, it's on the inner lip higher up near my urethra. I know it will heal quickly because of blood flow down there, but should I take any precautions to prevent infection? Can I have sex? How should I try to prevent bleeding and how long should I let it bleed before I get worried? Let me know what precautions you took if you've ever accidentally cut yourself.
