Am really curious about the "movement" issue. none of my models actually 'Move" in the strictist sense of the word, rather they seem exert a very subtle caress of the prostate resulting in the very exciting sensations. I can introduce movement by various methods of contracting but find that that is defeating the more subtle sensations thus, I stop that and depend strictly on very minor contractions mostly created by breathing.
So, am I missing something here ??? by not experiencing more pronounced movement??
