I could certainly love a woman without regard for her weight, but sexual attraction, for me, is thoroughly wrecked by obesity, and significantly diminished by the milder term, chubbiness. Personality can redeem the woman if it smolders and sizzles, but only to an extent.

Sexual attraction isn't fair, especially where love is involved.

Edit: I should add that a woman's weight doesn't matter so much as how it is applied to her physique. A large woman can be stunningly beautiful if the fat is favorably distributed.
