RS, I am happy you have found a way to keep your libido going so strong into your 60's, and like the others, I agree that you should continue to enjoy it to the fullest without questioning it, if it works for you!
It is good that you are true to yourself by not being in a relationship with a GG who wouldn't be able to meet your needs in the same way as CDing does.
But as a GG in a fairly new relationship with my bf, reading your post and most of the others who experience similar feelings to yours scares me because it does not look as if you need to have women in your lives. For the type of love that brings emotional security and companionship perhaps, but not for passion. You have yourselves.
Many GGs share the fear that we are not enough ... that our CDers will never feel as passionate towards us in the long term as we feel towards them, because CDers' love for themselves as women elevates them to a high beyond compare. Any woman would love to have a man (or a woman if she is so inclined) feel about her the way you describe you feel towards yourselves dressed.
If I am reading it incorrectly, I do apologize. Or, maybe it is not true for every CDer, but I venture to guess that if what I have said is true over all, it may explain why marriages fail eventually even after the SO has been supportive of the CDing.
