Just because I shaved down there it means I'm cheating??

Ok so I usually keep down there at least trimmed but not bald. It irritates my skin to much to keep it bald. So I usually cut it bald here and there for special occasions or just to surprise my man. Well he made the comment that it was getting long so I cut it all. Now out of the blue the swear I'm cheating just because I shaved. He never said anything about it before, why now?!?
