If your cat is not altered, there is a good chance she is pregnant. Her mammary glands could be swelling in preparation for filling with milk.
You can use an antibacterial cream on a cat's sore nipples. The cream will help to heal the sore nipples.
Squeeze on her nipples.
Your boobies are growing
No. A male cat's nipples do not produce milk so never "dry up" in the first place. A cat's nipples are part of the body.
I think the standard issue number of nipples is 8, but I just noticed my cat Dwight has 10....apparently this is quite rare !!
No. Have to look around the genital area. Ask a vet or another adult. The only way you could tell the sex of a cat by looking at the nipples would be if it is a nursing mother cat, in which case the breasts of the cat would be hanging lower and filled with milk. Otherwise a male cat's and a female cat's nipples look pretty much the same.

Male cats do not have prominent nipples.
It means your cat is a girl.

That she is or was suckling kittens.
