"Does the middle-aged or older, naked body of your long-time spouse still attract you?"?

(disclaimer) This is not a question about liking someone by their appearance if they are not your partner and have not been for 15 years or greater, I.E. been together since college or high school and now middle aged or older. The length of time you have been together and grown to love each other aside from physical attraction is not pertinent to this question. If you have not been in a long-term relationship greater than 15 years *with the same person continually, this question is not for you. This question has nothing to do with me, or any woman I am involved with, as I am not attached.

Your spouse that you have grown older with, over a span of 15 years or longer, when you see them naked does their body still evoke the same excitement as years back when you met when younger? If their physical body doesn’t do it for you as it did when you met them in college, in high school, or when you were 15 or more years younger when it comes to intimacy how or what do you do to get the libido revved up?
