You Are Not Alone!!! The first two years after I started taking Adderall for me it was a miracle drug not only did it give me the energy to do my job but it's made me happy to go to it and like you it helped me in social situations I could have talked to the president and not get a bit nervous. But then it happened I started watching porn and jerking off very often for example one day I sit in my zero gravity chair placed in front of my big screen for about 6 hours I never got out of that chair. I don't know what brought on the excessive horniness when taking my Adderall but I wish so much I could go back like I was.
Your brain has just learnt to associate (link) masturbation/sexual pleasure with the adderall. It's a very difficult connection to break once made, unfortunately, but it's not impossible.
Lots of us have gone from the horrible 96-hour wanking stage back to productivity, over time, but you do have to take back control and forcibly stop yourself from doing anything sexual and to instead MINDFULLY bring your attention back to the tasks and activities you actually planned to do.
