Hi, Sebby
The pictures seem to be in the order of maleness starting from the left. In the first three you pass, although the third from the left is on the androgynous side. While still somewhat androgynous the hairline and the way you carry your head in the rightmost one makes you look most feminine (in it you look very similar to a male friend of mine did at that age—his expression when he laughed was almost identical).
As for age, I thought you looked around 13 or maybe 14 in the pictures—which makes sense if they are two years old. That said, I live in Asia so elsewhere people may perceive you to be younger. Anyway, at that age bone structure has not really differentiated so expression, hairstyle mannerisms and clothes would probably be the main determining features.
