Guys what is considered "Big Boobs"? - samantha anderson 38g stream

I'm 5'0 "115 lbs and 36D ... It looks good on me ... but in all reality is not so great.

I see porn stars as Samantha Anderson, Brandy Taylor with ****. big saggy but what (as "tits" and men really find this type of natural disaster-D / G / F as attractive as chicken fat, what they tend to be) and if the SAG?

For me, I can not believe that there is nothing sexy about it.

How large is "large" or what is so important in the human body?
