True belief must be accompanied by action. This is done because A) you believe reality actually resembles your belief and therefore action is a rational step, or B) to test and see if reality matches your belief so that you might adjust your beliefs to match reality. In either case, a belief which remains only in the mind has no power unless it is acted upon.
There is a certain kind of bonding which ought to take place in a relationship; cementing on various levels of intimacy. Spending time together, holding hands, hugging, kissing and so on, ideally until the day of marriage. When we skip past the other things and don't allow those small moments of intimacy to settle in, we miss out on a number of benefits and often find our relational and intimacy cravings only satisfied by sex.

For those of you who also grew up in the south, there are some common experiences we both likely shared growing up in the Bible belt: hellfire and brimstone preaching, potlucks galore, youth trips where sex and alcohol were the norm (not for me though), and the occasional guest preacher or youth conference designed to really stir things up and get the congregation on fire for Jesus.
