The last few years of my now defunct marriage I was celibate, not by choice. Wasn't a good situation, I'm sure it wasn't a great situation for her either, but the one thing she could have done that would have helped us both was be willing to talk about it without becoming upset or defensive.

If you want to be celibate that is a perfectly valid choice on your part, though will change the nature of relationships (could be for the better).

But the thing that struck me was the title of your thread "permanent celibacy" why not say for the forseeable future I choose to be celibate, but leave open the possibility that you could change your mind in the future. Just seemed a very "black and white' way of looking at things. Being open to possible change doesn't mean that the current situation is bad, or that it ever has to change

Sex is always a difficult subject, it touches on feelings/emotions/triggers in ways that we don't fully understand. Closing off the option for change might inhibit personal growth.
