Non-Fiction Book Ideas on Marriage/Sex

I am in the process of starting a new commercial site on marriage and I have found in the past the best way to write a book is to outline a book with a killer premise then outline each chapter and sub-chapter, then make each sub-chapter an article (or blog post.)

So I am again asking you, my blog friends, to help me choose the most compelling book themes from the ones below. In your comments list the numbers of the top 2 title choices you like as well as any ideas to improve them.

Thanks in advance:

1. Charisma – How to be the person everyone wants to know (By the way, I know this doesn’t have lots to do with marriage, but it’s a book I’ve been pondering for some time…)
2. Mutual Fulfillment: How to Have the Marriage of Your Dreams for Life
3. Full Tilt Marriage: How to Have the Marriage of Your Dreams for Life
4. Your Next Honeymoon: How to Have the Most Romantic, Sexually Fulfilling Vacation of Your Life on Any Budget
5. Sexual Intimacy: How to Have Mutually Fulfilling Sex for the Rest of Your Lives
6. Hot Marriage: How to Have Mutually Fulfilling, Explosive Sex for the Rest of Your Lives
7. Peaceful Intimacy: How to Stop Arguing and Start Enjoying Your Marriage
8. Partners: How to Stop Arguing and Start Enjoying Your Marriage Partnership
9. Finding Peace: Understanding and Living with the Angry Spouse

Again, thanks in advance for your input.
