Is it normal for my breast to periodically expand?
I'm not sure if anyone has asked this question before since I think that this is so strange.
Basically, I'm minding my own business when suddenly my breast start expanding about 1.5 times larger than they were.
I'm not doing anything out of the ordinary meaning I'm not partaking in any activity or behavior that would cause a sudden growth or expansion such as getting horny, touching myself, having sex, perverted thoughts,etc.
So long story short, is it normal for my breast to just periodically expand for no apparent reason at all?
