My father remarried, and my new stepmother moved in. She appeared kind and gentle, yet carried a hidden sensuality. But soon, I found myself troubled by something—whenever she cleaned up the dishes, she'd expose her cleavage or deliberately position herself so she could see my crotch. It was as if she was teasing and provoking me on purpose. How should I deal with this? I'm a man, after all, and this situation left me completely confused and overwhelmed.
