It goes something like this:

The ideal is the standard we are taught to strive for. Close enough is a socially acceptable failure to achieve the standard set.

Perfect Ideal (ie: #1) = Abstinence until marriage. “close enough #1″ = intimacy once engaged to be married.

Dropping the standard for the ideal to #2 abstinence until engagement; “close enough” #2 becomes committed, relationship.

degrading further to Ideal #3 “committed relationship” / close enough #3 becomes ‘feelings of love’

Ideal #4 ‘feelings of love’ / C.E. #4 ‘i like that person’

#5 “I like that person” / #5 Close enough = anonymous, casual ‘because it feels good’.

#6 casual & anonymous / #6 = aggressive, vulgar unspeakable acts

Cheapening of the Ideal results in the magnifying and normalizing of the perversities.

I wish I could remember who I could attribute this to. Perhaps someone else may remember.
