Sounds like you're making good progress both physically as well as mentally.
In beginning to reconnect and rewire with my bride, we made a mutual agreement up front which consisted of the following:
1) No goals or expectations
2) No pressure
3) No disappointment
By embracing that, we were both able to relax and realize that neither of us was looking for anything in particular. We're just reconnecting and letting things take us wherever they lead us. If we end up making out a little and simply falling asleep together that's okay. If we end up making out a lot and actually engage in intercourse that's fine too.
Because of my chronic PIED issues, I knew going into the rewire process that there would be times that my body simply wasn't going to respond. By mutual agreement, that's okay. And because we were able to remove the expectations and goals we were both able to relax and enjoy whatever happened.
As your time together this weekend approaches, find a way to mentally dismiss the outside world and immerse yourself fully in your time with her. Lose yourself in the moment. Just the two of you. Try not to think of or dwell on how your body may, or may not, respond. Enjoy whatever it is that happens.
If you're able to do those things, I think you both will be happy with the results. No matter what they are.
I'm 72 or so days in and I can say that the PIED is getting much better. There are times it still taunts me, but I've gone from a consistent zero to 75-80% ability so that's a big big step in the right direction.
All the best to you sir.
