But seriously, women have a sixth sense and have a heightened sense of smell, just as one example.
Kenny Chesney has a song out which includes the line (I'm paraphrasing) "A woman can tell when her man's been cheating. She can smell the other woman all over him."
Some years ago, I came home from a business function one night and my wife smelled a strange perfume or cologne on me. She asked me a few questions, which I answered honestly, then told me to come to the bedroom where she had me strip naked. After running her nose all over me, she pronounced me clean and proceeded to make passionate love, which lasted at least an hour.
I can only imagine what would've happened had she sensed cheating. I remembered this episode if the thought ever even crossed my mind.
Shower ,,,a lot ?
Think about Lorena Bobbet.
