i also grew up in a very conservative christian home. My family would absolutely die if they knew what i do with Master...

Yes, it eventually goes away. One of the things that helps me is when i talk to other subs/slaves and even other doms (with permission of course).

If you ever need anyone to talk to PM me, i would be more than glad, i am somewhat of a newbie myself but i have gone through the conservative home and can definitely relate.
