[Between the Lines]

Don't you guys think one can lead a moral and happy life by, say, having a series of maybe 20-50 consensual affairs starting whenever you start these days and 26, getting married at 28 (having lived with hubby for 2 years), having 2 or 3 kids in wedlock, having a rewarding career, being monogamous during marriage?

Only if we redefine moral.

[Linda Liberty]

The meaning of a word is the disjunction of its separate senses, not the conjunction. Thus your behavior can be moral without being chaste, even by the dictionary definition you post. Chaste is one sense in which the word is used, but there are many others.

Moreover, meaning 6 is on its way to being archaic-- most dictionaries mark archaic definitions, something seems to be wrong with yours. :
