Yes! What does age have to do with it? As long as the parts are still under the garment and don't droop out, makes no difference.
No, they don't.
Oh my god something I never wanted to think about thank you
I do it quite a lot, especially if I am wearing something tight (panty lines) or if I am going out with my dear husband of 32 years I wear a dress or skirt sans panties. I just wear appropriate length skirts and sit lie a lady. No one needs to know but us. We love having "our little secret" and he just LOVES it.
