There's no right or wrong, mate. Everyone is different so eventually you'll have to find your own path. It's a good idea to get professional advice if you can find it and to cast around for other married rebooters, to hear their stories and see/feel what you think what might work for you.
I'm not active here but on YBR (your brain rebalanced.com) which is similar to here. There's a couple of long-term rebooters in the over 40's who've healed there marriages. Saville in particular as he had similar trust issues to work through because of his cheating. And 40new30 who, come to think of it, you might find on this board also (he was here for a while, anyway). Both of those guys are incredibly supportive and would be happy to help, I'm sure.
I'm single and have remained on almost zero stimulation for the last 218 days. As I understand it, 90 days is just an average and from my observation is generally only the period it takes for fellas to begin feeling better. The full process can take a lot longer and in fact appears to have time lines similar to other addictions (blokes who are two and three years clean still noticing changes). My plan is to find some beautiful she over the coming months with whom I can connect and begin rewiring my brain away from pixels (and my hand) towards real sex and loving connection. If that doesn't happen, at some stage I will consider experimenting with self pleasure but will be very mindful to avoid even fantasy because of the danger of slipping back into unrealistic expectations.
Personally, I'd stay off the toss for a while longer to give yourself the best chance of rewiring properly. If and when you do go back to it (or start orgasming with your wife) beware of what they call 'the chaser effect'. It's where orgasm (or it can come from having a pmo or subs slip) fires up those old neural networks and can bring on cravings or urges.
Have you looked at Gary and Marina's site Reuniting? It's all about reconnecting in relationships and probably has some good info that might help you and the missus in rebuilding trust and intimacy.
Listen: I've pulled back from being so active (even at YBR) so if I don't get back to you in a hurry, that's why. I hope what I've offered can help, some. You're doing really well and imagine you and your wife will get back to reconnecting and building trust if you stay on the path. It must be hard for her. You're lucky she's stuck around and is supportive, imo.
Good best of luck, till soon, mate.
