Depends how muscular I guess. Emily Blunt in Edge of Tomorrow is perfect form and function for a slender built woman in my opinion. Women (like men) come in different shapes so it changes per build as well. But bodybuilder/Arnold Physique in a woman is in my opinion unattractive, a woman's body just doesn't look right for big muscle builds.

Being Heterosexual means you like va**nas, and that applies to tomboys.
liking femboys is gay af even if they dress up like a chick because they got a dick, (excuse the delay)

it really much normal to being heterosexuals
