...Your mouth is bleeding way too much:

• DO NOT FUCKING SWALLOW YOUR OWN BLOOD, MOTHERFUCK.
  Okay no but seriously, this could cause you nausea (and vomit) and eventually some blood disease if you drink way too much of your own blood for some time.
• Put some cotton on the wound.
  Sounds dumb but it works, make sure to change it every 2 hours or you will get a nasty infection
• For the love of god don't suck too hard.
  Even if you really wanna suck dick. Wait until you're fully healed, you don't want to snap any sutures and cause more bleeding and excessive pain, do you?
• Don't force yourself.
  This could also snap your sutures and cause more bleeding (and pain), at this point you'd be sick of tasting blood.
• Avoid fatty food
  That includes nasty McDonalds, junk food, red meat, fried stuff, anything that's got too much fat. You will cause an infection in the wound.

I'm a dumb kid, I know these from experience.
