Agree. His ancient god is restrained from emotion for God knows how many years and he has the burden on his shoulders. He is supposed to be very very very very old and the way he walks, a step at a time can be interpreted as very old, very steady and with 10 mount everest on his shoulders because he is very aware of his burden and restriction. If he suddenly just throw his clothes and kiss her like he needs oxygen, it wouldn’t be consistent. The passionate part is the scenes after the kissing starts. You can interprete it as increasingly passionate as they go along.
