an excuse for guys to check eachother out, some say the game is fun to play, but this is just a rationalization for the expressing of homoerotic emotions, through the comforting medium of sport. Appraisal of other males can be conducted during the game and also after in the men's locker which is sporty and fun and chemically involving as opposed to in the men's bathroom which can be psychologically invasive and shameful as society has conditioned us to view our bodily functions as uncultured and unspeakable. Homoeroticism in men is as natural as it is in women. A correlary for football in women is competitive trampolining.
Football is a useless unwatchable abomination of a sport as is trampolining for women, but I let my husband watch it because it helps him to establish wholesome connections with other men through sport who are also ashamed of their secret attraction to other men.
