Uh-huh. This is assuming you have a significant other. I realize that a lot of people do, but it's not a given. You do not need a significant other in order to love, nor does love need to be exclusive.

There's love and then there's just lust. Love can include sex or not. I'd say that sex makes up about 5% of the average person's life experiences which can truly be defined as "love". (It is a nice 5% though, don't get me wrong...)

If we reproduced by budding and pollinating (courtesy of the bees) like many plants do, our movies and books would be quite different, wouldn't they? "Love" would have to find different modes of expression in popular entertainment.
