is freeballing bad for you

Yes. If you freeball too much your nuts will rot off. The boys require at least two protective layers when you are out and about, except in special cases like swimming where the water can slow down the crotch rot action.

If you can't see the potential issues with going commando, and furthermore you need to seek advice from the apparently almighty Google, living is bad for you, and you should consider stopping that.
