Logical fallacy. That's not what the quote you used states.
The quote states that "people with quality X tend to not do Y." This does not automatically mean "people without quality X always do Y."

time_management says "in my experience" so unless you can produce a universal quantifier for your claim, or do some sort of analysis to define cardinality, you can't invalidate what he said.
Wait, what? I'd say it pretty much is a universal quantifier.
The better point for tm to claim is most chaste women are moral, whereas the same cannot be said for unchaste women. So, to guarantee a better chance of developing a relationship with a moral woman (i.e. more likely to not commit adultery and be temperate), we men should be chaste and look for chaste women.
This is probably what he intended anyways, since it makes more sense.
