You don't HAVE to bother trying to be with someone of the opposite sex. There is such a thing as homosexuals. Ofcourse, sex should not be the ultimate goal, a partner to spend your life with is, atleast to me. I am one of those world-hating people, but the world seems not as bad when you are with someone you love and care for and who loves and cares for you back. I figure, I want someone to be old with, and since I don't really want to have sex while I am too old, I still want that loving person with me.
