It can stay on after sex, some get it stitched back on. Muslim men often check the sheets for blood rather than the hymen so women usually splash blood on there.
Not the women in my family though.
Lol who lied to you hahahaha
It's the mother in law who puts the whites bedsheets right before the first sexual engagement for those cultures who do that. So how does she splash blood btw there is no man who will stick his dick in you before he takes a look on your couchie.
Don't even try that lol
