When you open the Steam page:

Quote

THIS GAME MAY CONTAIN CONTENT NOT APPROPRIATE FOR ALL AGES,
OR MAY NOT BE APPROPRIATE FOR VIEWING AT WORK.

The developers describe the content like this:
“This Game may contain content not appropriate for all ages. It contains General Mature Content, and may include Nudity or Sexual Content.”


ESRB rating:

M for Mature

BLOOD AND GORE
PARTIAL NUDITY
SEXUAL CONTENT
STRONG LANGUAGE
VIOLENCE

Buyer beware.

Personally, I don’t like sex in my RPGs either, but if you look at games like Dragon Age and The Witcher it is clear that lots of people do. It’s pretty common for a major M rated RPG to have some sex content in the game.
