Um, that is not what medical science says.  Not a scientist myself but read up on it - there are a few people born with chromosomal variations, such as xxy but most people are born female - xx or male - xy.  

They are saying during pregnancy there are surges of hormones in the womb, exactly how that process of releasing hormones goes is genetically inherited.  That is going to result in the differences in both physical form and expression of sexuality.  So the idea of fluidity doesn't really sit well with that if it is supposed to mean fluctuating between being a man and a woman.  And a process of expression is underway by the time you're born.

Which sex you are physically attracted to seems to me to be equally stable.

In basic terms same sex attraction puts a person at odds with their procreational self doesn't it. 
 

Bisexuality is not the same as intersex. Chromosomes establish sex, but not sexuality. Sexuality is generally not a medical, but a psychological thing. There is some statistical evidence of genetic or hormone predisposition to sexuality. HOWEVER, there are far stronger links between certain genes and, say, obesity and yet for many of those genes nurture always wins over nature when it comes to phenotype expression (i.e. whether the person is obese or not). Likewise, if we look at statistical evidence of genetic predisposition to sexuality - there are some links, but no rational scientist has ever stated that there are genes (or prenatal processes) that MAKE you gay, rather something that is likely to contribute to you becoming straight or gay. I think the only danger in pedaling "nature" in public discourse is that people will decode they can "cure" homosexuality. You can't! It forms so so early in life and it is often impossible to tract what impacted it. While it can shift and change later - it can never happen "on demand".

On bisexuality, look into psychoanalysis - in that school it is pretty much axiomatic that a child is born bisexual. Psychoanalysis is one of the most widely used therapy approaches. You are correct, many/most adults really don't feel fluid. Their sexuality developed and "stabilized" usually by the time they are out of their teen years.

The interpretation of bisexuality in psychoanalysis is, however, quite different to modern pop-psychology or to bisexuality as a sexual identification. This last point does my head in, because my husband (who identifies as bi) and I are seemingly aligned on "everyone is a little bit bisexual", but are quite different on what it means and what to do with it. I have not formulated all my thoughts on this yet, but I might one day write a research article on it... or at least a forum post haha. It's what's been preoccupying me recently quite a bit.
