That is not a question. Atheists view friends as friends.
Suffering and dying exist. Existentialism has no part in atheism.
This does not really have to do with extentialism, But we atheists view sexuality as a healthy part of an adult's life.
There are no categorically atheistic views on any topic except a general lack of belief in gods. Apart from that atheists are simply people. They do not all think alike and with one mind such as theists. You have confused atheists with theists who generally hold religious beliefs as a group.
What you have described is simply a family that does not believe in gods.
Sexuality exists, just like new, fun big words!
The atheist existential view of ethics is that ethics do not emerge from supernatural sources but from pragmatic sources; a good system of ethics is one that contributes to the healthy functioning of the society which adopts it. In other words, we are ethical because it is useful to be ethical, not because God commands us to do so.
There is no atheist position on this and many issues. Atheism only is the position that there is no god or supernatural powers. As far as sexuality, atheists may be celibate, promiscuous, monogamous, polygamous, professional or any other sexually related position. Atheism has no comment or control on a person's private life.
Any atheist is a person who simply doesn't hold a belief in a god or gods. As such, he or she could have any belief about suffering or death, because atheism is not a belief, and it is not dogmatic.
Atheists have no "standard" position on anything except that there is no-good. All other questions on social order, work, and the existence of aliens is up to the individual. Posing a question on their views is like asking what bald men think of vanilla ice-cream
Money and career are different among demographics, so the opinion of such also differs. Secular humanism, as a philosophy, really has no bearing on either; money and your job are objectively measurable and assessed.They are necessary to thrive.
That view would mirror the rest of society. There are monogamous atheists. There are celibate atheists. There are promiscuous atheists. There are homosexual and heterosexual atheists. The same applies to any other grouping of humanity.Atheists and many other people view sexuality as a part of human life, not subject to the arbitrary demands of any deity or the control of government.This does not mean that secular humanists are necessarily promiscuous. There are practical reasons to exercise caution about sex:sexually transmitted disease,unplanned pregnancy,jealousy or other emotional problems,child support paymentsLike most secular activities altruism and reason, not morality , is the guiding principle in play. Self determined control is the important issue. This precludes the control of sexuality among consenting responsible adults based on "standards of morality" or government regulation.Atheists do not care if someone is gay or a lesbian or anything that may make you different. You are who you are because that's how you turned out. Many have become Atheist due to religious hate against sexuality.
