I've not had anything embarrassing that I'm aware of. At the beginning when I dissociated a lot I would worry about if I had wind or anything and didn't know what was going on. She also didn't realise at the time how much I would dissociate. I remember once her stomach grumbled really loudly and I wrapped my arms around my stomach as I thought it was mine and felt embarrassed until I realised it was hers.
I always worry about starting my period so if I'm due on I always wear a pad just in case and if I'm on I double up as I'm paranoid about leaking in there. I have had I discussion about periods when I was 11 and she was good but I get really embarrassed and can't talk about periods if I'm on due to my past probably
