I firmly believe its a responsibility of mine to keep myself in shape, good hygeiene, good self care etc to the point that my wife still wants me. It's sort of like your saying I think? If other strsnge women my age and younger desire me, then I know I am fullfilling that part where I keep myself put together enough that I am still desiable to my wife. I think its awful if one person in a relationship lets themselve go to the point they simply are undisierable by the other person.. Most times though, it seems like both people let themselves go eqaully..
All this being said, I know for me that I must be attraccted to someone physically and personaility/intelligence to be attracted to them.. I also need to feel like I should respect my partner in order to be attracted.. I coulnd't be with a women I didn't respoect..
All of this I feel I need from a women as well. I need them to maintain themselves to the poitn they are still attractive to me.
I think its similar to what your saying??
