I get that you feel like it's "sex" and so you don't want it, kiss, lube, in, out, finished, done nothing to look forward to because, you know exactly what is going to happen.
I get that the vibrator, makes you feel wet instantly, no lubricant, even by just touching it, that's because your in control, you know that you can change movements, slow, fast, where you place it etc, and not know how your body will react, it could be different each time.
There are three types of feelings, sensual/sexual and plain horny.
I'm going to suggest you try to please yourself beforehand, and see if that helps, and to suprise him stand in your kitchen, with a dress on, nothing underneath, bend over to pick something up so he realises and ask him to take you there.
Next time, touch yourself in front of him just briefly so he realises. Hopefully he doesn't kill the moment and tell you not to.
But, point being, go back to being a teenager with him, often, with different positions you take charge.
See, if he starts to change his patterns.
The main problem I think is you now view it as "sex" and it doesn't interest you to do that, there's no excitement.
Take control, don't talk, actions speak louder and see if you can bring it out in him.
Don't think you have anything to lose.
