Conclusion
Laurie's problems are twofold.
The girl wants sex outdoors. This is not uncommon. The outdoors can be very exciting because it is a dangerous place to have sex. It can also be sensual because of its beauty. However, most people use the outdoors as a change of pace. Most people settle for outdoor sex when they happen to have a secluded backyard at their disposal, and find it exciting because it is different from their usual bedroom setting.
While outdoor sex can be good for variety it is a problem on a full-time basis.
Laurie's other fascination seems to be in playing the part of a girl who has been forced to 'serve'. She is not only completely at the sexual mercy of the man involved, she is also a servant because of the desperate position she puts herself in, (a shipwreck victim).
This is doubtlessly a reaction to the fact that she is a spoiled girl who always gets her way with men by whining and whimpering, (her own words). Neither of these positions is a very healthy one. It is not good for a woman to be a servant, nor is it good for her to be a 'castrating bitch'.
This girl's main hope here would be if she is able to find a man who is strong and understanding enough to develop a healthy 50/50 relationship with her.
