Teens - Confessions

My name is Shannon. And I am addicted to porn. I just watched a half hour video of two girls (yea.....girls) and I thought it was the best video ever. I always watch girls. The guy ones I am not a fan of. I love hearing the girls and i wont go into more detail cause it might be a trigger. I masturbate too. Even without porn I still do it. I always say to myself and to God that I am going to stop, but then I do it anyway. I pray for forgiveness, then I do it again! I feel like I am taking advantage of God's gift to me. I hate it! Plus I look at the girls in the videos and think how much I want my body to be like theirs. I feel like it tearing me apart. This is something that I dont know how to get out of and I need help. I dont know where,who, or how, but I need it. Every time. I say "last time" and every time, I do it again! What can I do!?!?!?!? Also I am bi and I dont know how to overcome that either!!!!!!!!!!!!!
