Men have nipples because all embryos start out with the same basic body plan, which includes developing nipples before sexual differentiation occurs.
Men's nipples serve no functional purpose in terms of reproduction or breastfeeding. They are a result of embryonic development and are present in both males and females before sexual differentiation occurs.
Men's nipples do not have a biological function in terms of reproduction or breastfeeding. They are a result of the way embryos develop in the womb, where both males and females start with similar structures that later differentiate into male or female characteristics.
My understanding of this begins with the formation in utero of the embryo. All human embryos start out bipotential which means that embryos have the potential to become either sex. As a female will have an endocrine system that will eventually consist of breasts, men too have the same endocrine system. But the hormones in the male will stop male breast tissue from growing into milk-producing breasts. In short, men have nipples because they are the same essential creatures as females. What parts grow into what is determined by chromosomes, genes and sex hormones.
No, not only mammals have nipples. Nipples are also found in some other animals, such as birds and some reptiles.
No, mammals cannot survive without nipples because nipples are essential for feeding newborn offspring with milk.
Men don't "have to," but it is weird if he does not because EVERYONE, men & women, have nipples.
Most gay men enjoying having their nipples pinched, sucked, bite on while having sex. Overtime their nipples will become more erect and grow in size. A: What rubbish! Gay men's nipples are just the same as any man's.

Men are hard-wired to look at / notice/ stare at breasts and nipples in almost any circumstance or surrounding.
Yes. We are mammals. That happens.
its because when you are a zygote then you can either be a boy or a girl so the nipples develop anyway
