Sex can get messy.
I'm sure most Catholics have heard of cases where a spiritual director took advantage of an unsuspecting soul and imposed his own interpretation of JPII's Theology of the Body during the course of a spiritual healing session in which sexual contact was appropriate, right? Wrong - I mean, that would be wrong in any case.
I've heard a lot of crazy things said in the name of Theology of the Body, and a person really has to be careful sometimes. However, I can offer you a good rule to follow: If it doesn't feel pure - it isn't - especially if things get, er... ah... sticky. Failing my advice, New Oxford has a good article on the density of JPII's thought embodied within Theology of the Body, written by Fr. Thomas Becket Mullady, O.P. - It sure sounds to me as if Pope John Paul II never changed any of the rules about sex, no matter how many pick-up lines guys can adapt from his writings.
The "theology of the body" is one of the principal legacies of the pontificate of Pope John Paul II. The Pope systematically presented this extensive teaching in his weekly Wednesday audiences in St. Peter's Square from September 5, 1979, until February 9, 1983. Many well-meaning orthodox Catholics have attempted to explain this teaching and its theoretical or practical impact. They have been motivated by the same desire as the Pope: to defend the teaching of Pope Paul VI in Humanae Vitae in a new systematic way that takes account of Holy Scripture and sometimes uses a method of exposition derived from 20th-century phenomenology. Unfortunately, many of these attempts suffer from a lack of clarity, which has led some people to erroneously conclude that John Paul II's theology of the body is so revolutionary as to contradict Catholic sexual moral teaching. - Source
