1. I take back what I said. It doesn't have to be protected sex, just get real good at pulling out. If you choose protected sex, let her buy the condoms.
2. Always make her drive. I realize this causes dangerous hazards to you and the community, but it will leave money in your pocket. Gas is expensive.
3. Either make her cook, or make up an excuse about not having money. If she doesn't like it, you've chosen the wrong date.
4. The more attention you pay to women, the less money you will have. Think about it.
