Is it me or does anyone else think how messed up their childhood must of been to be w/g's doing doubles with their sister
sad really
Or perhaps how non-repressed their childhood might have been? We all inherit out attitude to sex from our parents or carers through own upbringing. While for inbreeding reasons MF sex between close family members is a very bad idea indeed, that would not apply to two sisters or to non-reproductive sex in general. It could be that they were encouraged to open about sexual pleasure in a hippyish way. I don't
automatically see that as messed up, it depends on the context. My parents were old fashioned and we didn't talk about sex
at all. Perhaps that's why I am on this board now!!
