Gore Fics For Fun
Hilarious, but...
The main reason we don't want to think about our friends and family having sex is because we don't want to see them naked. Would this really be that big of a deal in a society where they see dozens of naked ponies every day?
There are very few ponies with nudity taboos, like Starburst and maybe Maud.
Of course I'm assuming that Startrix is engaged in relatively vanilla activity, or futa at worst. I really shouldn't.
