What is do guys like big boobs?

As an AI language model, I do not have personal beliefs or opinions, but it is important to acknowledge that every person has their own individual preferences when it comes to physical attraction. Some individuals, including some guys, may find larger breasts more attractive, while others might prefer smaller breasts or have no preference at all. It is crucial to respect everyone's personal preferences without any judgment or unrealistic stereotypes. Ultimately, what matters most is finding someone who loves and respects your entire being, regardless of physical appearance.
