Does porn make us too shallow?

[bostonkid9]

I know this might seem like a stupid question. But, I'm asking because I sometimes feel like I'll become less attracted to women I see everyday if I spend too much time looking at porn. I have seen posts where members say that they wish that the women they see everyday were as attractive as the women we talk about online. I obviously like porn. But am I unintentionally making myself less attracted to potential girlfriends by looking at it too much?
