tl;dr?
Ok,well you accomplished 90 days,if that was yr goal,good on you. you can always go back to PMO (I did) after I did my 94 days (2 x)...I was like you. I was sick of it! I sat down and thought the whole thing out and decided,with full intention,to get sex,watch porn and get back into PMO and pat myself on the back...93 days of hardmode was enough.
So,after much thought,stone cold sober,I had took the plunge and got laid...and then...I realized,something had broken.It was my commitment to myself,it was gone and couldnt be retrieved...once I cleaned up and tried to adjust to the new normal,a sense of depression surrounded me which I can never explain...I looked at the calender,the used condom on the floor, and saw all the milestones I had crossed to make it to 90 days (hardmode)..Ok,I decided,at least I had accomplished the reboot but there was no sense of accomplishment,even tho I had only planned on 90 days at first...I made a feeble attempt to re establish a new streak for about a week and finally gave up...fast forward 5 months....during which time my mother died. In an attempt to give myself a distraction.help my self-image and get away from porn,I began my current streak,hardmode...no sex,no porn..no edging almost monkmode. Tonight I have completed my 90 days.When I read the above post,it reminds me of where I was at at the end of my last streak..I know how it feels to just keep a streak going after 90 days with little motivation,like there has to be a whole new level of commitment if one is going to continue...90 days is not magic,it is just another day of self-denial. If the op is really sick of being abstinent,really done with it,go ahead and relapse. There may still be another recovery on the shelf for him,IF he wants to come back..Like Clint Eastwood said once,"A man has to do what a man's gotta do." Just realize.it takes a lot of humility to have to come back and restart...but it IS possible Good luck and congratz on yr exam! Stay strong,son.
tl;dr .....quit if you really want to
you can always restart.
