Why is it that some boys dont want to learn how to cook??????????

For a long time boys around me do not even want to try and learn how to cook. A good example is my cousin and he refuses to cook and the closest thing he does to cooking is making a sandwich.  He insists that only girls need to learn how to cook.  That whole idea is totally wrong, everyone needs to learn how to cook something atleast because cooking is a skill and without it we wouldnt have any food to eat.  Also when guys know how to cook it will increase their chances of getting a girlfriend because when girls find out you cook they will find that attractive. Hint guys so listen up and learn how to cook.
