A woman has a pretty face, she is beautiful.
A woman has a sexy body (a$$, tit$ and legs), she is sexy.
I see a beautiful woman and I see her soft, cute female female features, which I find attractive. But I see a voluptuous woman, my primordial instinct activates wanting to suck on her huge breasts, and penetrate her huge soft a$$. The sexy one is more fertile while the beautiful one is more feminine.
Both can come together.
