Newbie and need advice

Hi to everybody and first of all - sorry for my ENG. I really need YOUR advice guys.
Am 41 y old married guy who has a nice relation in his family: a sincere and loving wife and kids. And I LOVE and TRUST her a lot too. Due to the many problems, my wife and I have faced during our 20 years being together we were able to keep connected very well. Our sex life wasn't perfect but wasn't bad at all too. Due to her frequent illness and my common travels for the job it became worse with time. I started to watch porn and masturbate some 9 years ago and it affected our sex life even more and negatively, for sure. Few months I realised absolutely that my ED is related to porn and not to my health. I have checked me - my health status is GOOD. I am lean-fit, workout 2 last years constantly, T level is normal. But I have these issues to keep my erection during intercourses with her. I can get hard, but lose it after min or two. Now I started to reboot myself with no porn (I have deleted all files, blocked access to porn sites). Am on day 14 and I would say I feel quite good - no terrible needs to come back. I don't know how it will be in the nearest future.
I have one question. The real sex with a partner you love isn't prohibited during the rebooting process, but what about c2c with my wife when I am away for 3 months (surprisingly, 3 weeks ago when we were chatting on Skype she started teasing me for the first time in our relationship in that way and we both finished with a big O being online). I afraid she will start it again and I don't know should I do the same again or I should avoid it. She doesn't know am on the reboot. For me, it's a perfect time to do it while being away and very busy with work. It keeps me distracted.
Maybe its a strange question for you all, but I would appreciate any suggestions and advice.
THANK YOU IN ADVANCE!

Personally, I would advise that you don't do it. Even though it's your wife you would be looking at, using a screen makes it resemble porn more than real sex with your wife. It could easily wake up those porn desires after you do it. I think you would be better off leaving the video cam off. It would be better if your video camera was not working at all, if you know that I mean. If you are decided that you aren't going to tell her about your porn problem, I would suggest you tell her you'd rather wait until you see her in person and then go crazy on her then. Porn is hard to quit, and anything that resembles porn (also known as porn-substitutions or P-subs) can keep your neural pathways devoted to porn active. That's exactly what you are trying to avoid.

Thank You a lot for your advice. I think I will follow your advice and will not do it on cam.  I DECIDED to tell her about my bad habits and I SHOULD do it. Just I think I shouldn't do it being on Skype. After my "confession" there will be many many questions and it's not the best way to give all the answers not being next to her. So I have booked flights home for some serious conversation. Hope I did right decision. I will not be able to fight it all alone, I think and she should know everything, despite how difficult it is. I am sure openness is a key in relation.

Still without PMO without extreme difficulties
