I remember someone telling me that there is a Spanish saying:
"A kiss without a moustache is like an egg without salt"
I've asked a couple of Spanish friends if they know this saying but they didn't.
In any case, Spanish women are unfortunately renowned for the dark hair on their upper lips - not a good look. I don't think you'll find many men who go for female facial hair (even if they are open minded on armpits!).
