I accidentally walked in on my girlfriend masturbating to hardcore gay porn

I already knew that my girlfriend was into gay porn, but I never knew she masturbated to it. Today I caught her masturbating to gay porn and she was furious that I saw her in the act.<br><br>She looked at me with a face of shame and started yelling at me for walking in on her. I was in shock and needed to get out of there. I can't believe that she was masturbating to the sight of two well-groomed and muscular guys fucking. It's clear that I can't compete with that, so now I just feel useless as a boyfriend.<br><br>I just need some advice on how to deal with this situation.
