You’re living an unfulfilled life with her. She’s boring. Admit it, the reason why you watch porn is because you wish she could do all the nasty sweaty things you see in pornos. But she doesn’t it. You watch porn before you fuck her, you watch it before you go into work and immediately after, it feels so good to watch porn. Yet your lust for her is dwindling and your sex life is becoming more mundane. So leave her and feed your porn addiction. Live in jerk-off bliss to porn.
