I do it when the girl is on the rags and can't do it properly herself.
Makes things a lot easier for everyone.

No need to be self conscious, she's your gf, you've done more personal stuff together already.

My Demon revokes any prayer
He's grown contempt for love and hope
He betrays trust, twists truth and fair
Indifference is his way to cope
Engulfing sound of sensations
He quells with voices of despair
And muse of short lived inspirations
Flees at the sight of his cold stare
