A shower scene is seen but although "steamy" (from the water!) the only thing that is really seen is a brief image of a woman's breast pressed against a man's chest while they kiss.
A man enacts a "pantomime dame" style striptease act as a joke and his fake breasts are seen and these are pressed to a man in the audience.
A woman is seen upset. An adult can work out that she has probably been raped, a child might not realise, if they were watching, but certainly it is explained in the subtitles in the English subtitled version.
(There is also a brief scene with a topless "dancer"/stripper midway through the film.)
