If anyone (both female and male) want to imitate a pregnancy experience, then you should read this from a fake pregnancy website. Pretending you're pregnant in the three trimesters, women try to convince others they're pregnant to others. And I guess, mpreg can become more realistic if a pregnant male played these traits.
