NOTE: This is mainly so I remember this later.

I got to thinking about incest recently after a question was posed by one of my professors in a genetics class. Also I was reading some h-manga on fakku.net but I won't go any further into that. So I forced myself to take a logical view of incest relationships and how I feel about them. Firstly I realize that incest is more commonplace in some places in the world and is looked on as taboo in most western societies.

I then thought about myself and relationships with the opposite sex in my family. I am a guy and have one sister (two years younger) who I used to fight and rough around with as a kid. I almost never got along with her until I entered my second year of high school. Suddenly we had a much nicer relationship. But I've never found my sister attractive so obviously I would never consider a relationship with her. I conform to societies norms in this way. However I sometimes wonder if I am never attracted to my sister because she is ugly or for some deeper psychological reason I can't explain. If it is the latter, am I normal and people who are attracted to their siblings have something wrong with them psychologicly? Or is it more about the society we grow up in and the environment we are raised in?

While most people are appalled by brother-sister relationships we all like to poke fun at the whole cousin incest scene. This is not as taboo but still frowned upon by most western culture. I have been told by some people that if they weren't related they would have relations with their cousins. I have 20+ cousins and about a fourth of them are female. (my father's family is huge) Unfortunately for my investigation into my own mind, I'm the oddball in this huge family. While every other cousin has someone there own age the closest to my age are two years younger and four years older. Out of all my female cousins I have only two I find mildly attractive, one 4 years older and one 5 years younger. Again though, (perhaps because of the age difference) I find myself attracted to neither of these girls. Based of evidence from others though I may deduce that while we may be attracted to cousins, the written and unwritten laws of society keep us from acting on these attractions. On a somewhat related note I'll add that difference in age and length of time spent together may affect attraction.

On an ending note, it can be proven that every person on the planet is the product of some form of incest somewhere in their family history. If you were to consider that every person in your family was unrelated by blood and counted every ancestor for the past thousand years you would come up with a number that exceeds the number of humans that have existed in those thousand years. In a way a family tree's branches split and form together many times in a person's history. Of course if you believe in the biblical or scientific Adam and Eve then every person on Earth is related and all relationships are incestuous. Of course even the evolutuionary theory shows a very small original population, meaning people would more than likely be related anyway. Food for thought...

I'm pretty sure no one will read all of that but I don't care as it's mostly to remind me of my ideas for a debate meet.
