All ball pythons will wrap around you mine do it all the time they don't feel the pulse or any crazy thing like that. Do you feed the python in the enclosure you keep it in if so they will sometimes think when you reach your hand in there it is feeding time. I would get a tub and start feeding him in that for safty reasons. Also stop grabing her from behind the neck that is the worst place to grab them you can actualy break there necks if your not careful. get use to your snake wrapping around you mine are always around my neck or arm....
