Lust Time

I'm in Lust - thinking about him turns me on.

Thinking about him thinking about me turns me on.

Imagining him thinking about me thinking about him thinking about me turns me on.

Is this normal? Christian? Decent? Kind?

Thinking about his mouth turns me on.

Thinking about his mouth on me turns me on.

Thinking about my mouth on his mouth turns me on.

Thinking about his mouth coming close to my mouth so my mouth is on his mouth turns me on.

Is this healthy? Should I talk to someone? Should he be scared?
