As for a sub going into his/her first slave/Master relationship that would most likely be a step too far and he/she will get burned by it.
As a fantasy absolutely but for somebody just starting out the journey well in MY book it is a step(or two) too far.
I definitely agree that the positions are damn fine addon to a good sub/Master relationship but for most parts (and for somebody actually having a kinda normal life also) it isnt really practical nor working.

All the kudos to those that can accomplish it but for me.. not really. Might be the fact that I dont want a slave, I want a sub rather and my "other life" wouldnt work with the Gorean culture nor would I really want to incorporate it into it.

You would have to think for yourself there also. Is that something that YOU want to have for your life? Would it work? Do you want it to?

soo many questions to ponder there.
It seems a bit far fetched for me since you are just starting out feeling your sub side, but then again.. it is YOUR life and not mine so the only one able to really answer them is you.
