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".
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
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
Yes, in a way. Its the nipples that become hard.
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 the breasts are getting ready to produce milk for the baby causing them to get harder and bigger.
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 .
When you feel horny your boobs may get harder
They touch the breasts, because they find it pleasurable.
No, hardening breasts doesn't mean pregnancy.Taking a pregnancy test that tells your hormone levels is the best way to know... because FYI, pregnant women don't have hard breasts... and don't think that the milk makes them hard, because the milk doesn't fill the breasts until around the time the baby is born
