nipples???
If you really want to know why men have nipples, you should research it very deeply. There are men who have produced milk from their nipples. It may not make sense to us why men have nipples, but to God it makes perfect sense. I hope you aren't letting nipples on males stop you from believing. You should study the Bible, even study it to try to prove it wrong. The best way to read the Bible is to read it as a skeptic. But please, don't let something so trivial as nipples on males keep you from giving your life to Jesus Christ.
