Also, we had a short break in our relationship. Last week - after we rekindled our relationship - we were talking. She suggested I'd see a specialized therapist - she didn't even name which kind of therapy - for these issues as she suspects things will be triggered again in the future. I had just fixed an appointment with a sexuologist and was planning to tell her anyway (it was a coincidence that I got the phone call just half an hour before we talked) and she was surprised but happy.
In the end her fear of triggering things left me with the idea that I will indeed be amazed by her skill and knowledge and that this would trigger me again. A more reasonable interpretation would be that she is just worried, but I can't let go of this idea.
Anyway, she does not want to make love before my issues are more or less settled.

Last weekend, I told her I did not want to run away from my desires. She asked what had actually triggered me and it was her prudence in the first place that made me think that, if she was holding back, she would probably be thinking about non-standard things to do and that set off the thinking about her being extremely experience and skillful. I told her and she was more spontaneous after (but still hesitant to take things further). We had a great conversation about my issues up to the point where she said that she evisioned me as being soft and sweet and passionate at the same time. I told her that I believe things will be like when we kiss: soft, playful and sometimes wild and passionate. And that things would be anything except for boring. She confirmed: "never boring", this too has been quite the trigger.
