In swedish mythology we have a creature called the nude. He looks like a man, although sometimes he shows himself in the shape of a white horse. The water is his domain and he lives in rivers and lakes. He is very attractive and uses his looks and his enchanting music (he plays the violin) to trick people, especially women to come to him. They are never heard from again.
However if you play the violin yourself and if you're a man, he might teach you how to play as enchanting as he does. Although you will have to pay for it....
. Anyway we don't see the whole, naked figure so we can only suppose why he is so attractive
