I've namechanged for this as I'm embarrassed about it.
I've just been reading another thread which referred to abuse by an older sister to her younger brother and it got me thinking about my own childhood. I have a brother who is 2 years younger than me and when I was young (I'd say about 4 or 5 years old) I remember us kissing on the lips. I can't remember what I said to get him to do it but I remember having seen people kissing in films (I never saw my own parents kiss).
Then I remember when we were on a family holiday when I was 12, encouraging him to get in bed with me and we were hugging. My older brother came in and saw us doing it and asked what we were doing, giving us a weird look but he didn't tell either of us to get out of the bed.
Would it be considered that I abused him? There was never any touching of any sexual areas that I can remember at all, and I don't know if he even remembers it, he's certainly never mentioned it.
I was a bit of a bully with him (as some older siblings are) and I've always worried a little about what I did because I did push him into doing lots of things so I wouldn't get into trouble. Not that it worked, he was so well behaved everyone always knew that I was behind any of his bad behaviour.
