There are a couple of scenes where a man and a woman engage in sexual conduct. Both times involve the man grasping the woman's horse's tail, as well as female nudity.
As part of a BDSM exercise, a woman's arms are tied behind her back, and the stem of a rose, thorns and all, is placed down her throat. Her tail is being groped energetically all the while.
A woman sits nude on a bed. Nothing frontal is shown.
