Some good things about having small breasts is that the small breasts don't weigh as much as large breasts and so you're not weighted down.
I know a friend who has larger breasts and she hates it as she says the larger breasts are too heavy on her and make it hard for her to sleep as well.
The large breasts require large bras and do not look as good on her when she's wearing a bikini.
She wants to have her breasts get smaller through surgery and hopes she can sometime.
I would not want large breasts as I could not deal with the heavy weight of the larger breasts and prefer my small breasts.
I used to want larger breasts but now I do not.
Having large breasts can also cause neck pain, shoulder pain and even back pain because of the extra weight of the larger breasts.
With smaller breasts you do not have that problem and your back and neck and shoulder will not hurt as much.
