If you don't want the TLDR, the answer is simple: boobs are great.
All of them.
Now for the science!
For hetero males there are actual biological triggers that activate in a guys brain when confronted with boobs.
Brain scans have revealed that when straight men see cleavage, their brain’s reward system lights up. This is the same part of the brain that reacts to food, sex, social bonding, alcohol, drugs, etc.
From an evolutionary standpoint there are scientific theories related to general health, as well. In the distant past, a curvy woman was likely well-nourished and had access to food, making the odds of survival higher for her and the baby. This would have been highly attractive to males.
Women have known this for Millenia and leveraged it to their advantage.
With the right pair you could probably rule the world.
Hope this helps!
