Yeah, I agree. sexuality exists on this book, and robots and empire between Lije and Gladia, though in Robots of Dawn there WAS mention of sexuality between Gladia and... the second humaniform robot, I can't recall his name, who was identical to R. Daneel, so while yes almost all the robots were androgynous. the ones built as humaniform WERE fully functional, and nearly impossible to distinguish from humans except by behavior.
Sai, I have no idea why you are running across so much info about Asimov books being related to homosexual. though the partnership of two male police officers and the friendship they develop, might be a happiness for gay males. Asimov put sex into his novels.... I'd say rarely.
I have noticed though that you seem to have been tossing in a number of posts in this forum that to me seem like you are trying to get people to believe what you say is truth, and that what you say is the most unbelievable pap that could be regurgitated. trying for outraged response, or denial from the uneducated, whichever.
