What's good, and what knot...

[Misanthrope]

Hello, my partner and I are VERY interested in bondage, but neither of us have experience with what knots to use, and some logistical questions. We have some appropiate rope, just not the skill and knowledge.

For right now, I think we mainly want to go with tied to the bed in a spread eagle position.

What knots do you reccomend, how many times should the rope be wrapped around the wrist or ankle, and what's a good way to tie someone down, but still have propper access to the (female) naughty bits?

Any advice you can give will be greatly appreciated. And there might even be a pic of me appreciating it in the personal pics thread.
