I 🍇ed my GF

For context, I am someone who has always hated the idea of sex, I have always waited for the good person (who is my girlfriend now) to do it. It took a long time for me to want to do it and she understood me and waited until I was ready, it is now a normal occurence for us and I have no probleme with it. Two days ago, she told me I woke her up because I was finggering her, I didn't even remember doing it and she told me it wasn't the first time I did so. We then came to the conclusion that I was sleepwalking. But I still did this while she was asleep so she was in a vulnerable position

I have already atempted in the past, I have been good for a year, but what I did is making me want to punish myself
