how about enjoying both together?
For myself if I am enjoying a beautiful sunset, I am most likely being contemplative at the same time, while if I am enjoying the company of another, I am most likely thinking about either him or about us as a couple.
Enjoying the company of a beautiful woman is often expensive, a sunset costs nothing..
the sun set it will be forever beautiful and beauty in women adventally fades
You might lust after a beautiful woman but the sunset will bring you a sense of warmth and happiness as can being in love with the beautiful woman.
A sunset isn't going to lie to you or cheat on you.
b is way more fun
