Just think about how you initially learned about sex, about what you were told. This is not to imply that all lesbian sex is similar to heterosexual foreplay. Lesbians are as diverse as heterosexual women. Not all women have sex or achieve orgasm in the same way. To date, no study has shown any harm on children raised by lesbian or gay parents.
Offenders are disproportionately heterosexual men.
Lesbian relationships are no more transient than heterosexual relationships. There is no evidence that children develop their sexual behavior by emulating their parents. As they mature, children develop sexual orientation independently of their parents. Because of our laws, children of lesbian relationships could lose their non-biological parent if their biological parent died. Also, Canadian children have no right to the estate of a non-biological parent who dies without a will.
