I don't fear sexual content, on the contrary, but often it is added in a very bad and inopportune manner.
There is a time for sex and that is not in the middle of a bloody battlefield or in a cave while outside a mob prepares to kill the witch inside.
I mean, there's some in the Witcher 3, and they let you choose your dick/vagina in cyberpunk. The options were kind of shit, but it means they aren't that afraid of adult content.
It's possible they're telling the truth and think some of the content just wasn't good.
