Something that has such fantastic potential for terrific pleasure deserves to be enjoyed totally and protected from the possibility of some negative emotions that would rob it of its full explosive joy. You shouldn't have to worry about fear and shame and rejection and suddenly wake up to find that the bed is empty and you are used and alone. The only way to fully enjoy sex without fear is within the bounds of a marriage commitment. Distinguish between lust and love. Lust is interested in satisfying a selfish craving.
Love is interested in doing what's right for the other person.
Life doesn't hand anything to you. That means you have to plan it without worrying about how much it will cost or how long it will take. These are only obstacles and challenges that need to be overcome. But you'll never get anywhere if you don't know where you are going. You have to have a plan if you want to succeed.
