For a relationship to go long-term, 
We gotta wanna be in each other’s heads as much as we wanna be in each other’s pants.
I do believe that little statement might have something to do with making a relationship last forever.
Attraction 3D/360/24/7/365.
I wanna talk with you because I’m attracted to your insight/opinion/wisdom/perspective.
I wanna take off your clothes and meet your desires because I’m attracted to your soft curves and soon to be glistening chest and midriff.
I wanna.  You wanna.  
That’s a lotta wanna.
Mutual wannas.
Totally duo doable.
