This is really awkward, but when I was a child my mother used to have sex with her then boyfriend when I was in the room (and once when I was in the bed). I've never spoken to her about this but I do feel like I have PTSD from it, as I have intimacy issues.
I remember vividly them talking in a dirty manner to eachother, so it's not like they were trying to be discreet. I was between the ages of 6 and 8 at the times I can remember it happening.
She also used to talk to me about how sex is a good thing and it's what adults do etc.
Not really sure what my question is to be honest, I just needed to talk about it.
