The very first line is misleading: "The more groomed a man is, the more sexually attractive he is". Absolutely wrong! This is something that the cosmetics industry wants us to believe.
Sex appeal of men has nothing to do with shaving or even having a shower. But has everything to do with CONFIDENCE. I've seen some of the most clumsy looking guys scoring the max with women, only with their sheer confidence.
But it is true for women: Men never like women who don't take care of themselves.
Also, body odour is important to attract the right kind of partner. It is nature. Every man's body odour is unique like his finger-print. Men's sweat has his signature pheramone, and helps attract the perfect women for him. Masking it with a popular scent or body spray makes you just another guy.
So, beware of the ideas you read in the media, which is nothing but a paid mouth-piece for the cosmetics industry!
