Girls, What's your take on breast physics in fiction?

For a long time, breast physics have more or less been seen as a pariah in various works of fiction in certain parts of the world, especially the west. Though, I personally think we can view this with a bit more nuance. Breasts bounce in real life, and the act of them bouncing are not inherently sexual/lewd.

What are your thoughts on a female character in fiction (anime or video game) having breast physics? Are you only fine with them if they're realistic? Or are you against them entirely? Either way, why do you think so?
