Dating and time to leave
If her she calls herself Lady Sarah then your email should probably begin civilly and conventionally enough with "Dear Lady Sarah." Addressing her as Mistress implies a relationship with her that you've yet to earn. And if you've created a web page as I suggested above close your email with the URL.
State clearly and specifically what - if it was anything other than propinquity - that motivated you to write to her. More than just your cravings: that is just being pushy. Courting a Domme in certain respects is much like courting anyone.
If you know someone who has left the Church, or who is considering leaving, and I haven’t included his or her reason(s), please feel free to add…
For each item note how you feel: Let her know if you see D/s as a lifestyle or a form of play. The more honestly felt words you present about yourself the better your chances of meeting a compatible Domme.
That I've tended to get along with dominant women online is the only qualification I can claim for the following. Will pleasing another, serving her satisfy you deeply, make you happy? Or is it really having your shopping list of tortures and humiliations filled that matters most to you? But you need to be honest with yourself before you can be honest with the people you approach online.
Poor fellow, you've emailed countless Dommes and none of them write back. You've expressed your willingness to do "anything." What more could they ask? While some Dommes are only looking for lifestyle slaves others seek play partners.
After all, Mass should be inspiring and uplifting and if you, as a congregant, can’t be inspired by the rich history of the Mass and the fullness of the faith that is imparted in the Mass through Sacraments that include the offering of the Body and Blood of your Lord and Savior, well, then, by all means, leave the Catholic Church.
Check out the nearest non-denominational gathering in which you can be inspired and don’t give it a second thought that you only have a portion of the fullness that Christ left us because, well, hey, you’ll feel “inspired!
