I once spoke to a woman who was in a group for women survivors of sex abuse. All the women in the group were lesbian and had been abused sexually and/or physically by the male authority figure in the home. The woman I spoke to was not a lesbian, but had been abused sexually by both parents and all male siblings from an early age.
Ellen DeGeneres was molested by her stepfather but says it had no effect on her becoming a lesbian. Her former partner, Anne Heche, was molested by her father but has taken steps to heal and was married to a man. Rosie O’Donnell and her homosexual brother were molested by a relative but she won’t say who.
