I agree pier pressure for sex and dating pressure for sex can be heavy. Being a Christian has always been the best way but one which has always been filled with persecution and it always will be. My rejection for priesthood in my youth caused me to turn away from our church and lead a life where I did not care or try to be good or stay chaste so I had some pretty wild twenties and teen years.  I have regrets for that period of my life.   Truthfully, I wished I had waited.  Not due to shame so much for the sex but more I wish I had been strong enough with God that I didn't let the hurt pull me so far away from His Holy Spirit.  I don't think God demands we seek sex in marriage only for reproduction as Christ never gives this reason and even St. Paul never recommends people marry to have children at all but instead so they (both men and women) don't fall into sin due to some of them not being able to handle a life without sex.  I agree our culture puts to much importance on sex overall.
