Sticking Like Glue

Just to share with everyone what I felt today during pushing hands with my teacher. One of the principles of taiji is to stick to an opponent. Well, I think my teacher does that very well... and has probably reached a new level with sticking. Why? Because the other day, when my arm came into contact with his arm, I tried to change the direction of his force (which was coming at me) by drawing it downwards. What I felt instead was that his arm was stuck to mine, and it was like trying to rip my skin away from superglue... PAINFUL!!! I wonder if anyone out there has similar experiences when pushing hands...
