Apart from the struggle to actually accept myself as submissive and move past the associated shame, the actual act i have the most trouble with is using crude words about myself.

It seems like a little thing, but i found, and still find, it hard to use words such as cunt, slut etc when my Master told me to. i have never minded him using them - i love it in fact - but i still sometimes choke as i try to get them out of my own mouth.
