I mostly sit with my legs spread a bit but have no problem crossing my legs either. With a big dick, low-hanging balls and freeballing in loose pants, my balls rest on the seat inside my pants. If I cross my legs my balls stay on the seat below the lifted leg, without being crushed. My dick gets pushed up and ends up near the fly of my pants when I cross my legs. If my pants are tight then it all gets jammed in and squeezed, so I have to sit with legs spread or die in pain.
