Maybe your Master can explain to you what *He* likes. It is after all for His pleasure.

Google: Gorean slave positions. There are many sites explaining in detail the positions and meaning of every position.
But my Master preferred to change some elements in them to make it personal to us.

And what better fun than Him watching while you practise them in front of Him. Allowing Him to comment and and be involved in a ......eh......hands on capacity.... to say which ones He prefers the most.
