Yes defiantly, I am very attracted to huge boobs and am not ashamed that I have actively tried to date ladies due to their 'endowment'. Although not just boobs, sometimes their big ass as well or that I have discovered they have a very large vagina.
I know women have dated me mainly for my endowment and dont really take offence to it, its all preference at the end of the day and some people are just a good match for each other, due to 'good fit' preferences. Although I would add, the most attractive trait for me is that the lady is a size queen regardless of their physical assets, its just great when they tick several boxes and we are both very happy in each others company.
