Sounds like you are experiencing resistance to the subliminal you are currently using and trying to find reasons to stop listening to it by changing to something else, for whatever reason (you can find a thread about resistance somewhere). Or you are just generally anxious and just need to trust the process and stick with your choice.
I have overcome PIED with EHPRA 2.0, and I have read somewhere that DMSI contain a healing-package even better than EHPRA 2.0 do (don't take my word for it though). So I think that you will be fine using DMSI to overcome your problem.
Two things:
1) Don't watch porn. It's a hard habit to break but you do yourself a huge favor doing it.
2) Do some Kegel's to get more control over your erection. There is a great app for it on appstore called kegel-camp.
