That's strange. How many days have you been handling it? I don't really know how often you are supposed to handle it but 1-10 minutes seems fine, actually I think that was recomended by Cazador, Thamnophis, or somebody else (or maybe I read it online?).
By the way, my snake's musk doesn't smell at all. I picked him/her up, got sprayed, then smelled it to see what it smelled like and it smelled like nothing.
