What is why are boobs soft?

Breasts are soft because they are made up of mostly fatty tissue and glandular tissues. The glandular tissues produce milk, while the fatty tissue gives the breasts their softness and flexibility. The amount of fatty tissue in the breasts varies from woman to woman, which is why some breasts may be firmer or softer than others. Additionally, the presence of hormones like estrogen and progesterone during puberty and pregnancy can also affect the softness of breasts.
