Arrogance

We talk about ego like it's a bad thing, but you need protection from something. That being said, try to make the something go away.

Sexiness

Cool and detached seem to be the choice of many. Surprise! Many people have come to see intimacy and trust as sexy. 

Emotional Infidelity

Maybe it's okay to love everyone equally. People have such different sized boundaries around intimacy. 

Faking

Too tiring! You might think it's working but you're just selling yourself short at the end of the day. Close relative of lying but not quite the same.

Evolutionary Theory

Sex will forever motivate everything.

Change

Research shows that people generally aren't capable of more than a ten percent change.  If someone has changed a lot, you never really knew them in the first place.

Growth

Assume that you don't know everything about anything, but don't convince yourself that you know nothing or you're going to be held back with some serious questions about self esteem.
