I have a few questions to ask please!

Where we currently live we have access to a number of great private highschools where we will be sending the children depending on them getting in of course!

My biggest dilemma is single sex vs co-ed. The 2 private single sex schools which we are considering and have enrolled the children in are great and have fantastic reputations, great facitilities and the feedback from other parents is so positive. Both DH and I went to co-ed schools.

So my questions are:

1) If you had siblings of an opposite sex did you find that by going to separate highschools it had a detrimental effect on your relationship or did it enhance your relationship not being in each others pockets? - I was an only child for most of my schooling life and have this fantasty vision in my head that my children would really look out for each other, support each other etc in high school and that going single sex would cease this.

2) Did you find that by separating the sexes it presented problems in the "outside/social" world... as in you felt more awkward around the opposite sex as you wern't used to interacting with them much as young adults?

3) Especially for the girls, being all girls was it a very "*****y" envrionment?

Any positive or negative feedback would be much appreciated especially from those of you who have been through single sex schooling! Thanks heaps.
