Do you think you’re in love, or is it just lust? These two emotions are inseparable. Lust is responsible for hormones -- it's a natural way of bringing a man and woman together to mate. In fact, without lust, it's uncertain that perfect love between opposite sexes would have a chance to grow at all.
The concept of the sex connects the difference between the almost incompatible brain styles of the two sexes. Hence, lust can be seen as one end of a wide range, which may or may not end in romantic love.
Love is the most dominant of all human emotions -- inspiring, self-sacrificing and capable of creating emotional conditions that can make the man want to be a “better” partner. Men fight wars over lust, but they make homes and families for love.
