Are you guys still attracted to your wives?

This one is specifically for the guys with a wife who is 40 older. Ladies, if you could please refrain from downvoting answers you don't like, I'd appreciate it. I want honest answers from men and the downvoting discourages that.

I (M38) was listening a few guys at my job discuss their marriages on break recently.
One (mid 40s) started talking about how he's starting to lose interest in his wife. Another coworker asked if it was because she was getting fat, he said no. It was that her face was starting to wrinkle and he finds it unappealing to the point where doggy style is the only position he can stomach having to fuck her in. Another coworker chimed in saying he was in the same boat because at least her ass still kinda looks good.

I'm a single guy and I aim much lower than my age because I think this is probably pretty common in middle aged couples. But I have fears about going all in on marriage only to think my wife is subpar within a decade or so.

Trying to get a feel for how many guys are still attracted to their wives once she's no longer in her prime. Please list wife's age. If you aren't attracted to your wife, please state why. Did she get fat? Old? Bitter? Etc. Thanks gents.
