I think after taking my ob/gyn rotation, I had huge respect for females.
Women do things willingly that men could never ever do. They have babies, which is enough in itself. Women also wax, pluck, pierce (OK, men pierce too, but there's no accounting for masochism), and wear high heels.
What do men do? Nada. Well, tattoos, I guess.
I've seen too many women in excruciating pain while their husbands/boyfriends looked on with total lack of understanding. Men are babies.
