I'm not really sure as to the cause of that disparity. Maybe it just boils down to the natural way men and women work based upon countless iterations of biology: women want one man to satisfy their one need, men want every woman to satisfy their one need.
I'm probably wrong, as I often am, but it sounds reasonable. MtF's would want to date a FtM because he understands what she went through and can empathize and all that jazz. But a FtM wouldn't necessarily want a MtF because there are so many other options available because that's just how guys think. Heck, there is one question that every man asks himself, whether he realizes it or not, when he see's a member of the sex he's attracted to: would I tap that or wouldn't I?
Women are like old carbureted cars in that you have to do a little fiddling with the choke and get a rich gas to air mixture but not too much or you'll flood the engine it turns on and once you do turn it on you have to make sure you don't let the revs drop too low or you'll stall.
Men are like fuel injected engines with an automatic transmission: just turn the key and you're good to go.
Alas I digress. Back to why one should date a transguy.
I guess they have a mechanical advantage in that you don't have to worry about an early finish (though they still might go out for pizza afterward and never call you)
