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.
Yes he did. They were pierced earlier but closed so he had it done again.
If you're a woman you probably won't be able to breast feed.
Try making a list of pros and cons and ask yourself why you want to do so.
No.

A properly placed nipple piercing goes halfway down the nipple. You DO NOT pierce the areola, nor do you pierce close to the tip. Of course, this rationale is for normally sized nipples, because unfortunately some piercers pierce nipples that were never meant to be pierced. Go to a professional and have them evaluate it for you.
Yes hairy nipples are normal for Men... but for girls they usually dont grow hair around the nipples.
That all depends on your anatomy. Your piercer will pick the size that fits you best :)
