for the girls to suck, while making love

no. men have nipples to prevent drowning when wading in water. watch men and you see them stop wading out when water reaches nipples, if we had buttons we would keep going and drown

Because in the womb, we develop equally until a certain point where our respective genders become more apparent. The period before this is when men grow nipples.\n\nBesides, can you imagine life without your nipples? A bleak world indeed.

Many answers.  Some guys like breasts because it reminds them of a safe place when they were children in the arms of their mothers (kinda gross, I know).  Others might like boobs because they like the idea of being able to touch that sensitive part of a girl that others guys can't.  You also have guys who likes to think of boobs as location of a kinky act.  The reasons are many.  I say they want to look, let them.  Once they start looking, we girls can get whatever we want from them :P

instinct..man's primal desire for breast...the sucking stage' in psychology.Get turned on big boobs because they are easily seen. But we can still be turned on even on small breast.Remember men are visual. There is rise on blood pressure..heart is pounding.

ASK THE EXPERTS: BIOLOGY   \n \n \n \n \n \nWhy do men have nipples?  \n \n \nAndrew M. Simons, a professor of biology at Carleton University in Ottawa, Ontario, explains. \nLike all "why" queries, the question of why men have nipples can be addressed on many levels. My four-year-old daughter, always suspicious of a trick when asked such obvious questions, answered: "because they grow them." In search of the trick answer, she quickly added that "chests would also look pretty funny with just hair." \n \n \nADVERTISEMENT (article continues below) \n \n \n \nEvolutionary biologists, whose job it is to explain variety in nature, are often expected to provide adaptive explanations for such "why" questions. Some traits may prove—through appropriate tests—to be best explained as adaptations; others have perfectly good evolutionary, but nonadaptive, explanations. This is because evolution is a process constrained by many factors including history, chance, and the mechanisms of heredity, which also explains why particular attributes of organisms are not as they would be had they been "designed" from scratch. Nipples in male mammals illustrate a constrained evolutionary result. \nA human baby inherits one copy of every gene from his or her father and one copy of every gene from his or her mother. Inherited traits of a boy should thus be a combination of traits from both his parents. Thus, from a genetic perspective, the question should be turned around: How can males and females ever diverge if genes from both parents are inherited? We know that consistent differences between males and females (so-called sexual dimorphisms) are common--examples include bird plumage coloration and size dimorphism in insects. The only way such differences can evolve is if the same trait (color, for example) in males and females has become "uncoupled" at the genetic level. This happens if a trait is influenced by different genes in males and females, if it is under control of genes located on sex chromosomes, or if gene expression has evolved to be dependent on context (whether genes find themselves within a male or a female genome). The idea of the shared genetic basis of two traits (in this case in males and females) is known as a genetic correlation, and it is a quantity routinely measured by evolutionary geneticists. The evolutionary default is for males and females to share characters through genetic correlations. \n\n \nThe uncoupling of male and female traits occurs if there is selection for it: if the trait is important to the reproductive success of both males and females but the best or "optimal" trait is different for a male and a female. We would not expect such an uncoupling if the attribute is important in both sexes and the "optimal" value is similar in both sexes, nor would we expect uncoupling to evolve if the attribute is important to one sex but unimportant in the other. The latter is the case for nipples. Their advantage in females, in terms of reproductive success, is clear. But because the genetic "default" is for males and females to share characters, the presence of nipples in males is probably best explained as a genetic correlation that persists through lack of selection against them, rather than selection for them. Interestingly, though, it could be argued that the occurrence of problems associated with the male nipple, such as carcinoma, constitutes contemporary selection against them. In a sense, male nipples are analogous to vestigial structures such as the remnants of useless pelvic bones in whales: if they did much harm, they would have disappeared. \nIn a now-famous paper, Stephen Jay Gould and Richard C. Lewontin emphasize that we should not immediately assume that every trait has an adaptive explanation. Just as the spandrels of St. Mark's domed cathedral in Venice are simply an architectural consequence of the meeting of a v

Nice decent women do not like for their nipples to show through except in the bedroom.\n\nIt is a natural effect caused by cool breeze, shirt rubbing against them, and from being horny.

It's because human nipples appear during pregnancy in the third or fourth week of development, well before the sex characteristics. So the nipples are there before you become a girl or a boy. But once you become a boy, they don't just fall off.\nNote: Kilroymaster: Please name your source. From what I've read, no male of any kind, human or animal, has ever produced milk.

My ex had 3 nipples. When he was a kid someone shot him with a BeeBee gun. Hit him in the chest and caused a scar that looked just like a nipple.

ALL nipples are sexy (thats' cause I love women so much, \nespecially their breasts). Leave nature alone, I'm sure you're\nbeautiful just as you are.

When we are concieved the chromosones dont distinguish between male and female until after the nipples have started to develop.\n\nWith women the cells continue to specialise and produce breast tissue with men they don't.

Somebody knows, ask an anatmoist. Nipples show up on a fetus before the fetus starts producing sex hormones (estrogen or testosterone). At this point in development the fetus is neither male nor female in appearance. Sex was determined at the moment the egg (X) was fertilized by a sperm (X or Y). This debunks the myth we all started female. As to why nipples develop so early, no one knows that answer.

The Straight Dope says, "To tell you the truth, nobody really knows. The best explanation I've been able to find (and frankly it doesn't explain very much) is that nipples aren't a sex-linked characteristic. In other words, nipples are just one of those sexually neutral pieces of equipment, like arms or brains, that humans get regardless of sex." \n\nIt's also notable that the fetus starts to develop nipples long before any other sex-linked characteristics.

Because your nipples are the most sensitive part on your body. Just like girls. Also your head of you penis and a girl's clit area. Mainly whats there is nerves that a very sensitive, obviously. Don't worry about it. It's natural.

please read the book entitled why do men have nipples\n\nthat will tell you why. It involves bacteria i think.

because men still have the capabiltiy to produce milk...it may be weird but through the power of suggestion or with hormones it can be done... and has already been done...\n\nmost people might say its vestigial but that wouldnt be so if its still fully functional... anyway hope this helps..\n\nps: perhaps one day in the future the need will arise for men to use them (once again?)

you should read the book why do men have nipples.  it askes a similar question and a doctor answers it.
