Genre: Drama, art-film?
Release date: Maybe 1950-1980.
UPDATE
The lone-man-among-many-woman element of the story is not the main focus of the movie, it’s mostly in the second half.
But that’s what they remember.
At the end, the old man lets out a number of inflated balloons from a window of the castle and they might have contained some semen. (Now that I’m relaying it, it sounds more like used condoms but they definitely said “ballons”.)
UPDATE
The castle might have functioned as a hotel of sorts.
The whole movie is set in and around the castle, it doesn’t feature ANY fighting.
The story takes place in the span of a few months, starting in the summer and concluding in September.
A young guy is lying in bed and a maid brings him food.
Eventually she undresses (no visible nudity) and climbs into the bed with him.
A few moments later, the father of the guy opens the door and he’s suprised by what he sees and he promptly leaves.
He later advises his son to lock the door next time. The maid gets fired.
Then the news arrive that the Germans have invaded Poland.
Every man is conscripted into the army but the young guy evades it somehow.
He and another man who is too old to be a soldier, becomes the focus of all the women in the castle.
They’re not the only men around but the story focuses on these two characters.
The remaining female servants and maybe even the female guests (?) eventually want to get laid with the young guy and many do. No actual nudity.
There’s a girl who is in love with the young guy but it’s unrequited.
