I don’t think that the Earth God (土地公) minds watching a bit of the old “in-out, in-out”; he’s a bit of a rascal himself. (Those puppet shows and outdoor films drag on and on!)
However, the Earth God’s Wife (土地婆) is a small-headed prude and doesn’t like anything which gets the old man off. You can count her against anything except boiled chicken and “gold-paper”.
I say, more boners for the Earth God. I can’t think of a more appropriate offering than semen and “peach-cave juice” (桃洞汁).
