A 20-year-old virgin girl’s normal breast size starts to get a little bigger. But it depends on the body structure. Know how normal breast size of virgin girl:-
20-year-old slim girl – 30 to 32 cup size A or B
20-year-old medium-built girl – 32 to 34 N cup B
20 year old chubby girl – 34 to 36 and cup C”
I am 26 years old, 4′11″ and 90 lbs. And either the 32C has a slight muffin top in my bra, or the 32D fits comfortably, yet snugly. Am I chubby at 90 lbs with low body fat?
In fact, there is no real correlation between actual breast size and shape. I know girls with fuller figures who are “A cups” and around 85 pounds. Equating a girl’s breast size to her build with “DD’s” is like equating a man’s penis size to his build. Like only chubby guys have dicks bigger than 8 inches and skinny guys have 4 or 5 inches.
Also, as the questioner asked, your status as a virgin has no effect on breast size, unless you are pregnant and lactating.
The main factor determining breast size is genetics, plain and simple. It is the same with penis size, hair color, eye color, skin tone and other characteristics of the human body for men.
