I'm in my 30s now, so perhaps I am out of touch with my younger self, but I don't remember being bothered by the idea of my parents sexuality.
Don't get me wrong, I don't think it's abnormal to be bothered by it. I've heard plenty of people joke about how gross it is that their parents had sex or whatever. I don't really understand it exactly. I guess maybe it's just an embarrassing subject!
Also, not to pile on, but don't look at your poor old dad's web history! What a nightmare! Lol
I use Lemmy because it appeals to my wish to be alone, by myself, with no one here beside me ❤️ social media peace at last.
