I think I had a very different idea about gender than you, since I think we're fairly equivalent mixes of "girly" and "not girly" but since I was brought up to believe that anyone could be physically strong, scientific etc, (in fact academic mindedness was gendered somewhat female at my primary school) but that boys were inherently violent, sporty, macho etc I decided boys were horrible and I only liked the company of girls. Then again, you were a much more violent child than me, so maybe not :D
