But surely trying to push something like this onto someone who isn't remotely interested is just trying to Dom from the bottom? Surely there should be a chat where you present an articulate and well thought out case for it, and why it would be beneficial to the relationship. Or if she/he is on the fence, ask them to think about it, or maybe find a few articles online for them to read and see if that might convince them to try it, but don't be too pushy about it.
If they say no, then it should be dropped, maybe they'll change their mind later, but trying to push something on someone that they have no interest in isn't fair to them.
