morally, it is wrong. and yeah, it is "yucky" in the sense that ur having sexual contact with a person of the same blood. i mean sex comes with responsibilty. what d'you go f*****g around with a family member for when you know that it IS wrong. incest is like eating flesh of ur own. love is natural for evry family member, so s** shld be out of issue when it comes to love of family.
tho im sure about step siblings.
