I've never had a girlfriend that likes porn... Or so thay said, but I'm pretty sure my last one has watched quite a bit, or else I don't know how she got all those ideas in bed.
However, now I'm single, and I watch all porn I want! When I've been in a relationship, I havn't had that big interest in watching porn, but if I'd find a girl that loves porn just as much as me, it would be so damn great!
