I want to be more submissive full time. GF isn’t receptive to the idea. Any advice?

GF and I have been together about two years. We live together, rent a home, have a 7mo old puppy who I love very much. Same with his Mom. However, there’s just one thing I wish I could change.

I enjoy being submissive in several ways. One of which is upmost is the feeling of being collared and cuffed. Especially knowing they can’t be removed by anyone other than the person in charge. I enjoy having them padlocked and want to wear them 24/7 .

However, my gf is not interested. She’s not nearly as kinky as I am. We’ve done a few bondage scenes before. Tried chastity for a few weeks last summer. It always fizzles out.

We love each other more than anything. But I keep looking to fulfill these desires in not the best places. Which isn’t who I want to be. I just want to be colllared for the one I love.

Any advice?
