Oh you’ve opened a nice big can of worms Richard!!

If we’re talking about gender segregation, yes homosexual behavior is more prevalent and noticeable in societies segregating sex. Basically, boys are stimulated by the boys and resort to this practice for sexual gratification (i.e. being overly affectionate to the same sex through touching, kissing, etc).

Having said this, isn't it true that when women are segregated based on sex they in turn become very reclusive and distrustful?
