It can be a slippery slope for sure. I am only 9 days with no P, no PMO, and no MO. Staying away from P hasn't been that hard, no MO has been tougher, but i'm sure i'll have my moments.
As I have mentioned in my journal I think I have related to your journal a lot more than others. You are much further down the road than I and hope you don't mind if I ask some questions. Are you still using ED meds to have successful sex with your wife? I am every time as I don't think I could face the frustration and embarrassment at this point. If you aren't taking them and having successful penetrative sex, then congratulations! if you are taking them what's your plan for eventually weaning yourself off them?
I feel your pain about feeling so inadequate as a man, husband, and lover because of PIED and to pour salt on the wound we did it to ourselves. I think this feeling of inadequacy has carried through to my friendships with my buddies, career and general well-being. I think I am starting to feel a glimmer of things changing in a couple of general interactions with people, I have found myself saying to myself something like "hey you have been PMO free for 9 days, you're becoming a man" and then stand up a little taller...LOL
