His AMA on the topic isn't too bad: https://www.reddit.com/r/IAmA/comments/3zt7ul/i_am_palmer_luckey_founder_of_oculus_and_designer/
unless the person who invents the holodeck is a woman... or gay, chances are fairly good that it won't be holo -men- involved in the way of having.
the gender of the image is irrelevant, as the person designing the system would determine the apparent gender, it is simply far more likely that the apparent gender of the first holographic sex doll would likely be feminine. This is of course merely a supposition based on the nature of probability, it is entirely possible that the individual who creates the first fully interactive hologram might be of Dihm like interest, at which point we can expect their first plaything to have tentacles. many tentacles.
