Cousins are legal though, so why wenchy's surprise?
I know it is legal but it's icky. These two were friends of mine when I was kid. They were practically brother and sister.
It's just a point of view.
When I was in my mid to late teens, I fancied one of my cousins (female) like mad, but coming from an Irish Catholic family no moves were made. It was only recently that I found out that she felt the same way about me.
