because when we are in the womb, the sex is not determined for a while so incase it's gonna be a girl, nipples will develop.

Nipples are a byproduct of men having nipples. Think about it: men and women are made from the same genetic body plan. The number of differences between men and women is a few as is necessary to differentiate the genders for reproduction. Nipples aren't a big cost to men, either.

-Nipples are especially sensitive and are a source of sexual stimuli, even for many men.
-Nipples are the result of an efficient plan of embryonic development. Human embryos contain characteristics of both sexes at first, because they all have basically the same genetic information. It is design economy. For example, in all human embryos, at first both the mullerian duct system (female) and the wolffian duct system (male) develop, because both sexes have the genetic information for these structures. Incidentally, this refutes the urban myth that human embryos "start out female."

The nipples of a fetus form before the male hormones kick in.

They're genetically encoded. Everyone gets them, and they happen much earlier in the development.
Really poor analogy, but perhaps think of it this way: while reading through the DNA blueprints, "nipples" happens in, like, chapter 2, whereas gender/naughty bits don't come along until, oh, chapter 45000.

I was going to answer this by being a smart ***, but then I really thought about it, and it's a very good question. Sorry, I don't have the answer.

When babies embryos from, for the first 6 weeks or so, the fetus is a girl's but it then devolps into a boy's if wanted.

I guess so that their chest wouldn't look so bare. But hay! They could be there just so their women can play with them during love making!
