Well, you feel two lumps on your chest and the area may be sore.
Not sure this is what I want to know
All boys/men like breasts and if you are unsure you could always ask him. rub them in his face and see if he likes it, i dont know
Look down and poke.
I don't know do you have eyes?
I don't know sorry :)
There is no way to know if any alien races have multiple breasts. There is no proof that alien life exists.
This all depends on your age. In women, breasts can grow until they are 18, sometimes older! If you are concerned you are pregnant, you will know because not only will your breasts get larger, but they will hurt tremendously!
See your doctor.
really?
I know that your breasts will become sore and your nipples and the skin around them will change color.
When your breasts grow, you will get a knot or lump in the middle of your nipple. If you hit it on a wall or desk, or anywhere really, it will hurt extremely. Even if they just hurt for no reason, they are growing.
The point is to hold the breasts in place. It is only pointless to wear a bra if there is no breasts. As long there's breasts, there should be a bra.
