How do any of those options preempt someone from talking about the morality of sexuality? All people experience sexuality in their own way. One of the big myths about Chastity within an over-sexualized culture (thats us by the way) is that the lack of intercourse entails a lack of sexuality. In reality, chastity is the proper way of living out one's sexuality which takes different particular forms according to different vocations. In marriage having intercourse with one's spouse happens within the context of chastity, but this is obviously no so in religious life. Whether or not they have sex, all priests, religious, married, and single people experience sexuality in their own way.
