I would like to recommend the book Love Without Limits by Nick & Kanae Vujicic. Not only is it the inspirational story of a man born without legs and arms finding the love of his life, but they have some good practical advice for both single people and married couples.
For those of you who would prefer to just read the suggestions and skip the story, see these pages: Single people: pages 3-7, 69-70, 77, 89-100, Chap. 8 (weddings), and Chap. 9. Married couples: pages 154-157 & Chap. 14
God bless you!
