It's wonderful when someone loves you, but that is just nothing at all compared with the enormous joy you feel when you love someone else. It is the one who loves who enjoys the most pleasure in sex (or even just in relationship) -- by FAR.
When you love someone, all you can think about is giving them pleasure and joy in any way you can think of. Do you know how, ordinarily, you are the center of your world? Well, when you are in love, suddenly your loved one becomes the center of your world, and everything revolves around Him. Every time you can do him any service or give him any pleasure, it fills you with joy.
Once you have felt this joy in your life, you will always need to have a boy friend to love.
So many people think about love and sex in terms of finding someone to give them love, but they are really missing out on the source of the real stuff.
