Whether you acknowledge it or not, sexual attraction makes the world go round!
Not to mention survival of the species.....
So, there is no point diminishing the power of sexual attraction of females by males.
It is there, it is ingrained and believe me, men notice.
How they handle it (no pun intended!) is up to them, but you can't pretend breasts or other parts of the female anatomy are not going to be noticed and admired.
Going back to the original post, if there truly is no interest or arousal under any circumstances, then I would attribute it to no sexual desire for women.
