I don’t understand why evolution would select for sexual fluidity.  But I know that non-human animals are very sexually fluid.  I guess because the sexual instinct is so strong in itself, and it’s a part of the enjoyment of life.

Maybe evolution doesn’t select for sexual fluidity, but playful behaviour.

Is it possible that all men and women are fluid when it comes to our sexual orientation? I wonder if sexual orientation is even a “real” thing…

It seems obvious that there is an evolutionary bias toward sexual relations that can pass along genes, anything else is frivolous in a sense.

Jake has responded best. A lot more investigation has to be done. While I have no doubt more people would be more open to different sexual experiences if it weren’t for cultural conditioning (most especially the horror of the Abrahamic religions that still haunts the world quite viciously in many places). Alcohol and prison does change things but…[Read more]

You guys and gals are mostly not addressing Ivy’s question.

Yes, sexual orientation is real. As pope indicates it is necessary in terms of evolution. Sexual fluidity is also real. However, not all humans are fluid.

I have not read many studies. But there are obvious ways to investigate the issue: anonymous polls, prisoners and especially…[Read more]

I think society has pushed us to a place where a majority doesn’t even understand the concept of sexual fluidity. We have almost boomeranged back to a place where people can open their mind to it and over time, I think sexual fluidity will become more natural and common.

In my vast experience, females are much more likely to consider engaging in same sex encounters as within the range of normality than males a…[Read more]

The book “Pleasurable Kingdom – animals and the nature of feeling good” by Jonathan Balcombe, about the emotional lives of animals, is very illuminating on this subject.

Animals are apparently very fluid in their sexual preferences and don’t care too much how they do it or who with.  They don’t have the social norms that humans do.

What is the natural variation in any species wrt sexual “preference”. At some point, even in humans, there must be a core natural preference to behave heterosexually, just for the sake of continuing the species. Any deviation from the heterosexual norm is due to either some natural variation or pathology–and in fact some “pathologies” may…[Read more]

I doubt it.

Asexuals are asexual. Strong heteros and homos are what they are. Prison is an artificial environment…if that is makin ya think as you are. And i assume that many prisoners are celibate by design.
