Astolfo is a male, it's not something one can deny no matter how hard they try. The reason why he dressed up as a girl is to slap his friend Roland back to sanity after the poor guy was rejected. He found the way he dresses to be cool or something after that, so he just keeps it as that.

You can go and watch Fate/Apocrypha to confirm it. Or search for a vid on YTB that has Jeanne seeing him naked.
