Just one mistake in the bedroom can leave you paying the price for the rest of your life. That's the warning of author Fander Banana in his self-help relationship guide S.P.E.R.M. S.P.E.R.M. stands for Successful Pullout Equals Rich Men. Banana advises men to do what they can to avoid "sperm scheming women" and focus instead on finding exceptional women. It's a reminder to think before you make that one careless decision that can bankrupt you financially, mentally, and emotionally. There are women out there hoping to turn a baby into a financial payday. You think you are hitting a home run until you have unexpected children calling you Daddy and a certain sum withdrawn from your paycheck every month. Having a game plan is crucial in a world populated with women with ulterior motives and deceptive qualities. Banana cautions men that many courts side with the women and suggests getting women to sign a prenuptial agreement before marriage. He also gives advice on how to use a condom and how to make sure you take your common sense with you to bed.
