"Adulthood Without Sex" by Phillip D. Harvey

"It is wrong to expect young people to be sexually abstinent until they are more than half way through their twenties."

But what if...oh, nevermind.

"Sexual relations are an important component of human happiness, and there is no moral purpose served by abstaining from sex if two people are mature and responsible."

No argument here.

"Why should they be deprived of sex?"

You tell me!
