Well, I've never really done tying for sexual purposes, but my dad did teach me a lot about knot tying when I was a kid, because we had boats, canoes, all those things that had to be tied up for storage. So I did learn a lot about how to tie a good knot. So, that being said, if you mean knots for sexual purposes (like tying your partner down securely) I bet I'd be good at it

We actually plan to get some of the purple rope Eden has for just that!
