Atheism and Morality: Sexuality

So I was just on Answers.com and decided to give an answer to a question of the Atheist existentialism about sexuality. I think it's a moral question which a lot of people find so inappropriate for most situations, but I don't feel awkward... ever, really.


So, this is what I said:
"As an Atheist, I think that there is no guiding principle in our lives beyond what we make of things. Because of this, the question is very arbitrary, let alone that Atheism has no doctrine or dogma to refer to because it isn't a religion or set of beliefs. 
Atheism is merely the label applied to those who choose the "off" position to Theism (the belief in a "god[s]"). It is not, however, the statement "There is no 'god[s]'.

Regardless, and because your question is quite vague, I will break it down into 3 smaller, more focused questions in hopes of covering all bases and answering as fully as possible.

1. How do Atheists view sexual behavior and heterosexuality?
2. How do Atheists view homosexuality?
3. Is there a set morality for sexuality?

1) How do Atheists view sexual behavior and heterosexuality?
Sexual behavior is something that is very prominent in human life, and in nature in general. It is something we all have an instinct towards; the instinct to reproduce is with us at birth and matures as we mature. Heterosexual people make up roughly 92% of the human population in the United States, while self-identifying homosexuals/bisexuals make up 8% (National Survey of Sexual Health and Behavior, 2010).
In my opinion, people should be free to make their own decisions regardless of sexual behavior and orientation. This applies so long as they do not impede the rights of others, do not harm others, can make informed and rational decisions, and do not discriminate against others for their choices. I do not personally agree with the laws of my state regarding sexual behavior of minors, but that may be slightly off topic. I feel this way because though it might be rare that the two consenting parties having sexual relations are both underage by law and mature/informed about their actions, this does occur and the laws still prohibit this.
Legislation being the way it is stems from having roughly a 70% Christian population and, religion being the way it is, this does affect the decision making of its followers. I feel that the laws should be reevaluated to represent the more constitutional, secular movement; as it does not have a bias and simply has a goal of making this country truly the "land of the free."

2) How do Atheists view homosexuality.
Homosexuality falls under this effect as well, though much more strongly in some respects. I believe that homosexuality, as it is natural, should not be discriminated against, nor should same-sex marriage outlawed simply because it does not seem "moral" to some people. I am not gay, but several friends and family members of mine are, and they feel the effects daily from religious (especially Christian) agendas about sexuality being pressed onto the general public. Again, religious views play a major role in the legislation of this country, however unconstitutional it really is to have it do so; and because of this, the radical fundamentalists often push their agenda successfully.
In short, people should be truly free to live their lives how they want, and not be shut down by those who feel it offends their personal deity. 

3) Is there a set morality for sexuality?
This entails more of a philosophical question of "Is there a 'god[s]'" in order to even ask the question the way it is, and because I'm an Atheist, obviously I would say "no."
As of current news and technology, there is no tangible or logical evidence to support the existence of any deity of any religion ever in history, nor is there evidence going against the theories put out by the scientific community concerning the origin of the universe as we know it, the origin of life, and/or the process by which new life forms arise (Speciation in Evolution by means of natural selection). By this and logical reason which is against the mere existence of an omnipotent, omniscient, omnibenevolent (in Christianity), omnipresent "god", I am an Atheist.
Finally, because I'm an Atheist, I think we should be defining morality not based on the will of an imaginary sky daddy, but instead on what is productive and liberating to the people of our society; humanity.
