Hi i am a 30 years old straight man , single don't have a lot of sexual activities . I have been masturbating since maybe age 14 or something and only had access to porn these last five years. Now the problem is i used to get hard by touching or being near women but i blame porn for ruining my erections , sure i can get hard when i am alone but when having fun with women i don't and its making me scared . I stopped watching porn because i know it messes up your reward circuit but is it enough ? will the 90 day abstaining challenge help me reboot my circuit and get normal erections or what ?.
