They met, fell in love, dated and waited until they were married to have sex.
There seemed to be a special connection between them that made me wonder, It started me on a quest to discover what I call "practical abstinence." All of the "true love waits" messages mean nothing if they can't be put into practice.
I haven't been able to find any literature on this subject.
The point at which a relationship takes a turn for the worse is when you spend less time exploring the most personal and private region's of your partner's mind and more time exploring the most personal and private regions of their body.
The relationship then becomes contingent upon your sexual compatibility, and the importance of your true personal identity takes a back seat.
That means both persons are interested in making sure the relationship develops without having sexually related things happen that are reserved only for marriage. For example, kissing on the lips for a few seconds can be a nice sign of affection and does not typically stimulate or arouse.
But a "French kiss" (a kiss with the tongue) or prolonged kissing on the lips along with pressing the other against you will naturally stimulate and arouse.
