We are all attracted to things that we find beautiful. Beauty does matter, but the good news is that people can be beautiful in different ways. Some people might be conventionally physically beautiful, others might be beautiful to one person but not another and still other people might have a beautiful heart or personality.
Beauty can be superficial or internal. It is a quality in something that elicits an emotional (and often physical) reaction within someone that is positive. Although beauty can cause jealousy, it is based out of the desire to see beauty in one's own world. Beauty can be artificially created to enhance a product of a certain environment and many tools are used to create it and in the sense of commerce, it shows how much it matters on that level. When it comes to relationships and attraction, beauty matters in finding sexual partners, but lasting relationships are beautiful and matter even more. Any way you look at it, yes, beauty does matter.
