Probably.
There was a non-spanking scene in a Tarzan movie I'll never forge. In a Pre-Code 1934 movie called Tarzan and His Mate we see a lot more of "Jane" - the quotes are there because most of the nude scenes involved a body double.
From Wikipedia:
In this pre-Code film Jane sleeps in the nude, swims nude with Tarzan, is constantly touched by Tarzan, has a scene in which she is stranded in the jungle without clothes on, and is seen nude in silhouette when dressing in a well lit tent. That Jane and Tarzan sleep together is all the more startling by Hollywood standards because they aren't married; the end credits list O'Sullvan as Jane 'Parker,' emphasizing that she was single and living in sin.
The scene that caused the most commotion, the 'underwater ballet' sequence, was available in three different versions that were edited by M.G.M to meet the standards of particular markets. Gibbons' wife Dolores del Rio had performed a risque nude swim in Bird of Paradise (1932), a sequence that is said to have inspired the one in Tarzan. Tarzan and Jane (O'Sullivan's swimming double, Josephine McKim, who competed in the 1928 games with Johnny Weissmuller), dance a graceful underwater ballet with Jane completely nude. When she rises out of the water, Jane (now Maureen O'Sullivan) flashes a bare breast.
