When I was a young boy of 6, a girl and I looked at each other's crotches several times behind a house. We then kissed under the covers and I got a nearly painful erection, but we didn't know about intercourse. I think lots of children have had experiences with kids their own age.

I wonder if you've ever considered the world view that monogamy is not the only way to be in long term relationship where you are committed to continue the relationship with that person? There are forms of responsible non-monogamy. You mentioned swinging, and that is one type, but for those that crave more emotional or verbal intimacy with multiple partners there is polyamory.

Sex at Dawn is a book that proposes that humans are not naturally monogamous and that monogamy was better suited to agricultural societies that are patriarchal.

More recently a study published found that there is a spectrum just like for sexuality.

I myself am heteroflexible and somewhere between swinger and poly. I don't have a strong desire to love many people equally due to time and energy constraints, but I realize that I am not a monogamous person.

So, how do you feel about people that decide that they are not monogamous, but that they are still ethical and good people?

Speaking of ethical, the ethical slut is a good book.
