While I don't adhere to waiting until married, I have always equated sex with love
This mindset will drastically reduce the number of "complicated/dramatic" relationships
Not to mention counter productive and distracting
There is a reason when ever religious text boasts modesty and discernment when choosing a partner:
It is vital to our evolution and integrity
It can be a vacation affair or the first time with the love of your life
But it will never be because it's an escape from reality, fulfillment for an empty soul or giving into pressure
Sex can cost dearly: a life savings of child support, the trust of others and even your health
Those who don't recognize this are fairly dooms in the realm of relationships, boundaries and self awarenesses
