The church is not encouraging marriage to deal with the issue. All I've heard is telling the young people to just ignore those desires, pray, think of Jesus, make yourself pure and holy.....none of these work. They are not practical for people in their late teens to twenties, when hormones are raging. The time to bond with the opposite sex is during these years. When you reach your 30's those desires are far less. At the time of Jesus, couples were married before they were 20. It had nothing to do with them not living longer. Jesus and Paul knew it was the physical desires. I wish I had done this in my 20's.
