Does it effect you love life? If it does than its a problem. some guys i know watch porn and masturbate before seeing there gf's so that they last longer.

Well if you had no idea about it... then its probably not too bad.
I mean its a problem when it starts affecting other areas of your life and relationship.
Like he has no time do to anything else b/c he's watching it...or never wants to have sex w/ you.. only masturbate to porn.

Too much is when your lying in bed alone and he's looking at porn. I don't have a problem with porn, I watch it myself. My wife knows I watch it and she doesn't have a problem with it unless it starts affecting our relationship. Sometimes we watch it together but it's not usually her thing. I absolutely adore my wife and she knows it. Making love to her is fantastic and porn doesn't get in the way.
My advice: Ask him while you are in bed together, tell him your concerns rather than confronting him. You might find it's nothing to worry about, it might even ignite something new in the relationship.

Let's look at this from another angle - how many steamy romance novels do you own? How many romance books constitute too many? Escape literature is escape literature even if it consists mainly of pictures. The reason why he's downloading, viewing, so much of it is ITS BORING. If fact it is sooo boring that you have to constantly change it out. Think of exchanging your library books every 15 minutes because each book is more of the same old, same old. Cheesy sets, inept and inane dialog, no plot, just naked people doing it this way and that way with close-ups, weird angles and poor lighting. She might be cute, but the men? "Oh, baby, you're so hot." Yeah. I'm sure he is, honey. Face it, he must be, because he's no Brad Pitt. Sometimes you can see the microphone hanging from the ceiling or boom because the cameraman is inept. How could anyone feel 'threatened' by THAT?
