First of all girly I have to say im sorry that this has been part of your life experience. You are not alone and we stand with you. I also have these fears too but the best thing I think we can do is learn about what predatory behavior looks like on children, teaching them to not allow touch on their genitals and learning abt what behavior in children looks like if something like that was to ever happen. It is very hard. I think it is reasonable to have fear especially having trauma yourself your thoughts are valid. https://www.bethesdaok.org/prevent ^here is a link that discusses molestation prevention and steps to take that I found helpful
I totally think about this- for years I said I never wanted children just because I knew the dark side of life like the statistics on how it's usually someone the family knows etc - and now im pregnant I've fully accepted the fact my child will not be changed by anyone else or left overnight or for long periods with anyone else or ever have any photos on social media or anyone to be sent photos of her minus my mum and she has strict instructions not to share them with anyone. It's heartbreaking but unfortunately I feel like it's the world we live in 🥺
