I think it is Great that your Mother is a Lesbian and thus so accepting of your Gay-ness. As to my Mother - I really regret not telling her that I would prefer men - she even asked me once if I did, but I didn\'t confirm it. She was really good at lecturing, scolding and reprimanding, so She wasn\'t someone I would tell about emotions and sexuality, nor ever ask her for advice about anything, though I would gladly have had sex with her if she wasn\'t so straight and maybe frigid (likewise with my Father).
