conflicted on what to do

So the last couple times i've had sex (or have tried to) I have not lasted long at all (i'm talking about not even a minute). Clearly this is extremely embarrassing etc. I'm conflicted on if I should continue nofap or if I should try and practice the "stop and go" method I keep reading everywhere to train myself to last longer and THEN do nofap or if I should just continue nofap. If i fap it would be without porn or anything at all and I've never had a bad addiction so that's not my issue. Any thoughts?
