With Venus in the 10th, he is under the control of his wife; if he stays that way, it is good, otherwise he is raw in the eyes and mind.

When Venus sits in the 10th house, the wife becomes the ultimate authority figure in the man's life. Dr. Sharma explains that this man will be completely under his wife's control ("biwi ke bas mein").
