A thought can only consciously be from your conscious mind, because it must go from your sub-conscious to your conscious for you to be thinking about it. Provoke one, you provoke the other. That is the point. Provoke the conscious with an interpretation of the sub-conscious, and suddenly they both begin to communicate a little better.

Sexual preoccupation can mean a lot of things Claire, without putting ideas in your head, could mean:

# Haven't had sex for a long time and want it.
# Have been sexually abused, hiding it, thus making it on your mind trying to hide it.
# Have been abused sexually and have not dealt with the feelings or guilt surrounding it.
# The list goes on and on...

Only each person uniquely can interpret what it means to them, and will do in their own time.
