I'm currently indecisive about body type preference. It's always been a preference to have a girlfriend who was slightly shorter to significantly shorter as I like the idea of them snuggling up against me at around chest height but that would be unrealistic as I'm not that tall.
However recently when playing with the idea of perfect offspring, I'd prefer my sons, should I ever decide to have children or marry for that matter, to be much taller than me as I aspired to be tall and my daughters slightly shorter than me would be acceptable. That's the thing with children, I tend to think people only have them in the hopes that they achieve everything that you yourself did not.
