That's really the key... The total mindset shift.

In a matter of seconds interest in sex, or intimacy in general, just collapses.  Not decreases, just straight goes to zero.  It's not a choice, it's just a chemical shift without control.

Imagine a hunger so fierce that you'd eat dirt just to have your stomach feel something.  And then you offered your favorite food.  That mind altering need.  You'd kill a man for that food and never feel regret.

We go from that to "you are full and a bit nauseous, and being offered stale food" almost instantly.  

Sex goes from being something exciting and a huge desire to being a  mechanical process and even just gross.   It's absurd and hard to really emphasize enough.  

That's why planning is key.  Focus on her first.
