How often in the buff?

46M, married almost 23 years. I was talking to my wife about (the lack of) showering together as it has been nearly a year. I explained that it concerned me that I have not seen her naked since then. Full disclosure, I’ve seen her naked once in the lat year, and twice in the past 5. There was actually a 3+ year span where the least I saw her in was her bra and panties. To me, this situation is unhealthy. I love her, desire her, find her amazingly beautiful.

We have sex in the dark. Always. Pitch black dark.

As I thought about this more, I don’t think I’ve seen her lower region (sorry, not sure what verbiage to use on Reddit) in over a decade.

Men are visual creatures and this bothers me.

Question: How do you approach this subject in your relationships?

UPDATE: We had a conversation Thursday about this and is relevant to the conversation. She wants me to ask in advance (i.e. schedule) if we're going to shower together. Also, we cannot shower together if the kids (16, 12) are in the house even though the shower is downstairs and they are both upstairs doing their own thing (reading, tablet time, etc).
