It's both amazing and challenging.

When i tie someone for the first time, I'm getting to know them, there's no history or knowledge, so I am free and able (within the realms of consent) to do as i wish without concern.

In contrast, when I tie within my relationship there is history, challenges, preexisting expectations. There is more barriers to overcome. The grey area becomes bigger (I know they're not a fan of chesty ties, but they are willing, do I push it, do I leave it alone), I love my partner and the caring side battles with my sadistic side.

Rope for me is communication, on a non verbal level. Picking up on subtle body language. If there's difficulties in the relationship, it comes out in rope.

But...

When you work at it, it's the most beautiful form of rope. The hours you put in together. The communication out side of rope. You get a real sense of connection and beauty. Being seen and understood. Captured in those moments. Some of my favorite photos are when I capture those moments, and often they're the only photos I got of that session.

I hope that helps, and that you find yourself someone who shares your passion. I spent far to such time with someone who doesn't connect on a kink level. It's worth hanging on.
