Hi kitty,
I have an online Master and there are a few things I do for him each day. I have a set task of doing 8 positions for him each day. At the moment I hold each one for 21/2 minutes. I have begun wearing a ball gag during the tasks also, mostly because I find them hard to wear and want to get more used to them.
Another task he has me do is to pinch my nipples for 50 secs each time I go to the bathroom. This is probably more suited to an online rather than a r/l relationship, as it is designed for me to feel submissive, even when I am at work.
I also email him every day and he will sometimes give me other tasks to do, like shop without panties or edge for him without cumming. It all really depends on your circumstances and what tasks are going to make you feel both submissive and satisfied too.
It seems you are off to a good start and I guess the key now will be to not rush or overdo things. The fact that you seem to have great communication, both face to face and via your journal, tells me you are on the right track.
Have fun and hoped this helped a bit.
