I'm going to hire a team of commandos to go out and collect DNA samples from select females (preferably through non-violent means).. such as Josie Maran, Jessica Alba, Laetitia Casta, and other contenders for hottest woman on Earth. Then I'll employ a team of unethical genetecists from Guatemala or China or somewhere, to create perfect clones for me (preferably disease-free and infertile if the science has progressed far enough at that point). I'll take the clones to a private secluded tropical island somewhere where I will raise them all on a steady diet of ricecakes and porn and teach them to worship me as their sexual god.
Though, this isn't really a fantasy so much as what I plan to do with my millions whenever I get around to making them.
