I am a teenager approaching my 20's.in 2015 one of my friends showed me porn videos as he was watching and he kept showing me for about five times that year and that was the last, then in 2018 during my vacation I felt those porn feelings getting back to me cause of the boredom and watching it affected me and I started watching porn too and now it keeps coming back even when you watch and see a beautiful girl or woman the mind runs to sex but though I have not been too much persistent on watching it cause am trying to quit, but when I watch porn I feel anal deep pain could it be the result of a fissure in me or its something else cause it has taken I think a year and more month since I started having blood in my stool. Thank you.
