I have a large skull, even for a male. I found this out many years ago when trying to find a hat for a Halloween costume. I couldn't find one that would come down to my ears and had to kind of wedge it onto me head, yet when my male friend who was the same height borrowed it, he had to use his ears to keep it up!
It doesn't bother me however. In Japan I've learnt that skull and face size =/= maleness/femaleness or beauty. A lot of people in Japan, male and female, have big skulls and big faces (i.e. wide cheek bones and temples) and they still look perfectly OK and in proportion.
For myself, I've learnt that it's not the individual size of any one part, but how it balances with everything else. For me, my large skull balances out with my wide shoulders and 'widish' chest. I have wider than average hips for a male (though still nowhere near a cis female) so I'm hoping with a little HRT they will work to balance out my shoulders.
As for my hands though, they look like someone cut them off a giant and glued them to the ends of my arms!
