Still a beginner with honing. I have a Belgian coticule and a slurry stone purchased off of a member here but I try and try and seems like all I get is water! Why no slurry?

I soak the stones and then try and nothing seems to build up.

How long should I rub the stones together?

My first opportunity to put in time for practice came during vacation. Even though I couldn't get slurry I worked with a cheap blade (A Gold Dollar) and got it to pop hairs off my arm after lots of strokes on the stone. However, it didn't take much off my face and pulled more hairs than it shaved.
