DAE wife/GF over react when she catches you looking at porn

[skywalker]

DAE wife or GF go crazy when they catch you looking at porn? I don't actually look at that much porn any more. but we only have one computer in the house and occasionally I leave something up on the screen. Then it turns into a whole big emotional drawn out thing. She is self conscious. I try an tell her it's a normal guy thing it has no reflection on her. WTF.
