My dear Old Vagina Lady. I will admit that the vagina, like the ears or forehead, are a part of the body and as such subject to the laws of time and gravity and aging, but a couple of years? Your vagina is not a time-lapse photography project. It's not like a plant with a shelf life of couple of weeks or months.
Sure over decades the vag may shift a bit. An outer labia sag here, an inner labia droop there, surely a tuft of robust black hair giving way to a Steve Martin and eventual Clint Eastwood, but worry not. Your puss is just as lovely as it was a few years ago. I mean am I missing something? Are you feeding it fudge every night? Does it wear bifocals now? Does it require a hearing aid and a walker to get around? ? Does it drool and have little patience? Vaginas are built like Fords: tough and durable. Meant to last over the long haul. Nut sacks on the other hand... not so sure.
In any case, snap away at your privates. I would also make sure your camera is decent and the lighting is nice. It is unbelievable how much more vibrant and healthy a face or genital can look using just the right setting.
