If you have hard balls at the end of your breast, they are growing. If there are little bumps that are hard it's breast cancer and if they are just hard in genral they are getting ready/are to produce milk.
I am pretty sure you can make them as hard as you want - if you have a "hard" problem, you can always find one that is even harder. If this is true, then there is no such thing as a "hardest algebra problem".
Depending On how big both your breasts are if there both about the same size as you hug they can bump each other which can hurt them,the preasure of breasts pushing hard into breasts can hurt them too,try not to let your breasts bump her breasts as you come together for the hug,also when together dont squeeze each other tight as breasts can crush breasts doing that,if your friends breasts are firmer than your breasts that can also be a problem,firm breasts against soft breasts can hurt too. Hope this helps you out .
Virginity has nothing to do with a girl's breasts. Breasts contains mostly fat and are soft but during puberty when you grow they can be hard at times.
I think because of breasts
They touch the breasts, because they find it pleasurable.
Although I've never really felt "hard" boobs, I'm assuming softer breasts are nicer to touch. My girlfriend's breasts are soft and supple and I find them very pleasing. Extremely firm breasts seem a bit unnatural to me.
look at there personality and if they have big boobs then great
Having uneven breasts is a common problem, however there are no health risk with it unless there is a lump causing the unevenness. If that is the case then one should have them checked by a doctor.
Yes, in a way. Its the nipples that become hard.
Yes the breasts are getting ready to produce milk for the baby causing them to get harder and bigger.
When you feel horny your boobs may get harder
You probably never liked her for her, you just liker her for her looks or......... whatever.
