haha you 're infected by porn addiction with the use of internet. I also know that your relations have failed or in verge of failing because of low sexual energy. It's a disease after the easy access of porn materials of porn in the internet. Sex is energy, the desire to have sex with a partner moves you towards your goal. You get up, look good, go to school, study hoping you'll find a good job one day and practically everything we do in our daily life is related to the sexual energy. You were designed to work for that enjoyment , but with the easy access to the porn you mind did not want to do hard work. why go to gym, look good study and get good job etc etc so you can be sexually/socially attractive to get satisfied with sexual bliss, the porn it few clicks and few clicks on your keyboard away. and in the beginning you fully enjoyed porn, because it was something new and exciting for you, but now your brain doesn't want to do hard work of getting real fun from the world and wants to get the quick enjoyment from porn, and too bad now it's used to of the same thing so many times it doesn't get excited by porn.so you are virtually walking like a zombie without no sexual energy. You can not maintain excitement in anything, not even real women. because getting a real women needs work , same with job.
the only way out is by quitting porn, and least not doing it for a month.when you abstain yourself from porn it is extremely important that you do not even try to see any thing little even little exciting, otherwise your connections in the brain will find the path again to the old porn habit. it's like someone trying to quite alcohol or drugs, a small portion will open the closed gates and lead you to the same old path.
