"There are many reasons women resort to women for sexual contact.

For instance, if she has rejection issues with her mother, she needs to feel affirmed by a woman.

Or as was mentioned earlier, she had a traumatic experience with a man/men that left her distrusting to the point of distraction severe enough to prevent her from achieving sexual fulfillment.

It is somewhat less frowned upon for women in same sex liaisons but still strong enough to deter the easy acceptance of this identity (lesbian)

true gender confusion comes from deep set emotional crisis and can be addressed if the individual wants to change them badly enough."

Although we don't always see our childrens' psychological issues correctly,
my daughter has been a lesbian for 9 years; but when she told me about it, she was distraught and confused, not happy at all. I strongly feel that she did have rejection issues with me, that for her the bond was incomplete somehow.
It isn't an easy issue to understand. It has been extremely painful, considering the research on shortened life-span studies in lesbian sexuality. I don't want to offend anyone here, just sharing my experience. She has ceased communication with me. Now it has become a tragedy.
