Why can't guys wear pink or admire flowers?

or say stuff like 'awww' or ''cutteee ! ' etc. without automatically being clified as ''gay''... why is society so messed up ?? why is the world so stereotyped??... why can't a straight man openly express his emotions for things he finds cute ??.... women can cry at movies, no big deal.. but a man can't. gosh... men are more under social pressure to hide emotions than women, believe me ! opinions....
