I'm a 19 year old guy and I just met my 20 year old cousin sister at a wedding that I haven't seen in a year , and even when I was only only on rare occasion.

Well the thing is, when I saw her, she was smoking hot. Alot of nasty things came in my mind. I'm kind of weirder out now. I thought there was supposed to be natural mechanisms that kept you from being attracted to your family members? But if the chance to get with her ever came up, I don't think I would turn it down. Is this normal? What should I do?

The relationship between me and my cousin is very weird. We are both of the same age, and therefore, every time either of us visits, we spend a lot of time together, but that relationship does not stay tight for more than a month, and then we forget each other. I sometimes think that I subconsciously let her go in order to forget about her...sometimes I think she does not care about me much and just fakes it.
