singletrackmind "Isn't "guy eyes" testosteronitude? Dudes going for lines a lot of women don't feel comfortable with?"

Funny, I wasn't thinking of aggresision at all I was thinking of spatial sense. My ex partner, a very butch gal which is very different from FTM she had no gender identity issues at all whatsoever so this is off-the-off-the-subject but she used to kid me "no, you're not butch at all, don't kid yourself, you have no spatial sense".

That's true, faced for example with a small car trunk and multiple suitcases I'm at a total loss. On the other hand I have a photo somewhere (one I haven't torn up jk) of her in front of her PT crusiser trunk with about 4 people's stuff neatly fit.

I don't think you can generalise about even this: plenty of women architects, engineers, in construction these days and we know that the lack of them in the past had to do with prejuidice in the fields not a lack of spatial sense.

But do men see space differently, "can I ride between that rock and the tree?"
