I prefer to sit with my legs crossed at the knee, it's always been more comfortable that way. When men sit their balls usually end up kind of resting on top of where the legs come together, it doesn't hurt. It will only make sense if you ask a man to sit naked in front of you and observe where they end up in different sitting positions. Even if your balls end up between your thighs, your thighs aren't hard (unless you are flexing them strenuously for some reason), so it doesn't hurt but is not ideal. Whenever this happens (for me rarely), you kind of do a little shimmy where you butterfly your legs open and closed a bit and that readjusts the boys back up where they belong. ok that's way too much talk about balls, hope I cleared that up for you :)
