I had not heard of GSA but my first cousin is very attractive and occasionally I have wondered what would have been the result if my family had been Arab as they very frequently marry their first cousins.

Also, I knew a Scottish girl who slept with her brother. She said that he had just been divorced and came home to stay for a while and was sleeping on the sofa and was very depressed so she went downstairs one night and made love to him as she thought it might help to cheer him up.
