why don't guys have boobs?

Men have more testosterone and women have more estrogen. Estrogen actually causes breast tissue cells to multiply. The more fat a person has, the more estrogen present in the body. That is why a fat guy or one with a high body fat percentage could start to develop boobs. \n\nAnother interesting fact... the more estrogen in the body, the less of a sex drive.

Because they lack testosterone

Both men and women have boobs but if you are referring to the unusual enlargement of the male breast (male breasts are supposed to be flat) then this means that they have more estrogen hormones than androgen hormones. Normally, men have a high level of androgen but genetic aberrations, obesity, infection, malignancy, hormonal imbalances due to abnormal conditions of the pituitary gland and the adrenal glands, may lead to an incrased secretion of estrogenic hormones in males manifesting as gynecomastia or an abnormal increase in the size and shape of the male breast. Generally, gynecomastia is not a serious condition unless it has been diagnosed to be malignant.

First off, I would like to ask you why you want them to become bigger. If it's for a guy or you think guys will find you more attractive...then that's a really stupid reason. Any guy should like you for the way you are and if he doesn't then move on. Think about it, you won't have to worry about buying a DD, your odds of breast cancer are slim, and you can fit into your shirt just fine. Be happy with what God gave you. Don't worry about your breasts so much...it's pointless.

Males also have the hormone estrogen. Estrogen menlarges breast size. Women have more of it, so they have bigger breasts. They also have luteniezing hormone which produces milk for mammary glans after giving birth. Men do not have that. Women displaying male qualities like beards have an excess of testoserone and androgen

Just in case you want a serious answer, men have nipples because during the early days of a person’s development (fetus) everyone is female. Males become males later due to hormones. The nipples are created before the hormones kick in.

Why Men Have Nipples\n\nFor the most part, nipples are on men's chests not for ornamentation, but because we all initially originate from the same kinds of tissues. By Louanne Cole Weston, PhD\n  \n\nMales and females, though very different, have a great deal in common. In the earliest part of our embryonic development, we all start out much the same. Though the sex of an embryo is determined when sperm meets egg, the genital anatomy of males and females cannot be visually distinguished with the use of ultrasound until the 15th week of pregnancy. \n\n\nFrom the beginning, we all have the tissues that later develop into functioning parts, depending on whether we are genetically coded to be male or female. (The genetic coding that leads to people who have both male and female anatomical traits is much more complex than we'll get into here.) \n\n\nMales have nipples because they develop with the capacity to be female should their chromosomes dictate. Females call upon this capacity when they hit puberty and their breasts develop. Later, if they become pregnant, they call upon it again as milk is created in their breasts. Generally, males do not have a reason for the nipple to function, although, from time to time, adolescent and adult males develop a condition called gynecomastia, in which hormonal levels fool the breasts into beginning to develop. \n\n\nBut for the most part, nipples are on men's chests not for ornamentation, but because we all initially originate from the same kinds of tissues. Males just don't need their breast tissue to be a functioning part of their anatomy

Silly question. The question "why do boys wear bra?" would be much more interesting!

They don't. Both men and women have mammory glands.\n\n\nhttp://www.newsandevents.utoronto.ca/bios/askus18.htm

Actually, every guy that I know (who isn't a womanizer) likes a little bit of softness!  And to tell you the truth, the only women I know who don't have a little lump are competitive athletes... and even then some of them do!  So be proud of your body and keep active and eating healthy!  Besides, I don't know about you, but I wouldn't want to date a man who was dating me for my body!

I actually do know this.  In eutero, your nipples are formed before your sex organs develop.  Women go on to use hormones to create breasts, but for men, there is absolutely no reason to have them.\n\nThat is the 100% truth...
