Weirdly, no...
HYE choked someone during sex?

Best advice on sex actually came from my grandma. It was right after I came out as bisexual.
Rough translation:
"When I was your age I couldn't be anything other than a good wife. People might look down at you, but your life won't be ruined if you go out and try everything you want. So why wouldn't you?"
Pretty sure some of the stuff I've done would've shocked her, but she'd still approve.
