When I was little my older brother used to beat me up all the time. My older sister would torment me in public, but at home she treated me with love and when I was about 8 she showed me what sex was.
My Dad hated us kids. Mom pretty much ignored us until my brother went on a rampage, then mom would baby us. Mom gave me bruise inspections in her room once a week when there was no one else in the house. I didn't realized until much later that her playing with my penis like that was molesting.
When my dad died and we were all together again after 20 some years apart my sister told me that my brother and dad were raping her almost constantly. My brother was also raping my mom and dad helped him. My brother was in prison at this time and mom was in a home for people with mental problems.
My sister apologized for molesting me when I was little. I said I understood and that she was only acting out. We parted ways and now keep in contact more than before.
Thing is though I have never been able to stay in a relationship. I never learned how to love anyone. Growing up I learned that if you like someone you had sex with them. I never learned all the social things you are supposed to do in between.
