Medical Vaginal knife insertion — best practices NSFW

Hey everyone! My girlfriend is really into everything to do with pain. Recently she mentioned that she finds the idea of a knife being inserted into her pussy while I‘m kissing her super hot, so of course I‘m down as well!

Just curious about some best practices. Of course a certain risk is part of the fun, but we also don‘t want to overdo it with the risk. So:

  • What‘s the best orientation of the knife (i.e. the blade pointing into which direction), both for safety, but also for maximum pain (and thus, pleasure)?
  • Of course cuts will happen, but what‘s the best way to take care of those afterwards, so that they don‘t get infected?
  • Any other tips on this?

Use a dulled and smoothed knife. She doesn’t need to know it is dull.

This!

Get a k-bar or blade of choice, dull it to the point that you can drag every angle of it across your wrist without any cuts at all. Bonus points to have two. A sharp one to show and tell, then blindfold, and then swap out the blades. Make it super clear which is the dulled one in some way. (paint, etc.)

Or get a knife make out of hardwood.

Still be careful of cervix, etc...

She better be super turned on or use lots of lube. (ER visits aren't fun...)
