Well I I've always looked at porn since I hit puberty. I recently got engaged to a girl that says she never knew and believes it was OK until I proposed to be her fiancŽ. She has looked through my phone and seen that I had been doing it again... She's been so upset about it and believes I done love her.. what to do

Apologize. Delete the pornographic material from your phone/pc and show her you've kicked the habit and got rid of the stuff. Keep repeating that you love her and are sorry.

That topic goes both ways. Im a girl and my guy watches it. It doesn't bug me except that I feel like Im competing with these pornstars performance wise. Makes me feel a bit like I'm not good enough or crazy enough. But overall if it really means that much to her- make a deal that meet both of your "needs".
