Pretty much my current relationship. (I’m not the one “being used” though.)
Reality isn’t always as sexy though: Your moods won’t always be in sync and your libidos won’t always match. That’s just human. But those times it all matches are just magic.
And for the other times: Open communication, toys and setting and respecting clear boundaries go a long way.
Many people like a bit of subordination/domination. As most things, it’s a spectrum and there are some people tending to either edges.
The two big caveats about subordination fetishes are however that firstly, such fantasies can be a response to trauma and/or abuse and secondly, it puts you in a very vulnerable position and leaves you very open to exploitation.
It’s the “comfy wholesome” part which really holds this together and makes it great: You’re putting an immense amount of trust and responsibility on your partner if you submit yourself like that and it can only work if your partner is fully aware of this, up to the task and really cares about you.
