Getting a girlfriend is weird

My reaction to a few things that used to shock me has gone from "aaaagh! What the fuck?" To "mmh, that's nice."
For example, I was leaning with my shoulder against my towel that was on a wall hook, and it fell across the back of my neck, and my surprised, unthinking reaction was to NUZZLE INTO THE COLD CINDER BLOCK WALL (college dorm) and growl a little.
Wat the fuck?
