Kissing scenes are very hard to pose but you can use look at me script for that then pose the head lips for kissing the script is posted by
Toxictitan on this thread check that
. Also for facial expression i am use dial presets called 101 expression library you can find that one website that shared you via dm for mesh grabber. Doing facial expression in the beginner stage are tough but once you master it then its not big deal everything required practice tbh. Also i agree with you creating one scene is time consuming in beginner days trust me my it took me two days for my first scene now i can render three to four scenes in a day.
I want to give one more tip you assign shotcut for pan and rotate in the DAZ and use them instead of that tool thing.
I assigned Alt+LMB to rotate and Alt+RMB to pan it will save you lots of time. You can also mirror the posses like by pressing control H it will save your time for sitting and other symmetrical posses to lean that in brief watch videos on YouTube.
