Is there a particular reason or strong piece of evidence that speaks to you on the subject of inborn orientation?
I've read some papers by psychologists who specialize in helping adolescents cope with sexuality issues, particularly sexual orientation issues. There's a lot of variation in how much weight they give things like pre-natal hormonal exposure, early gender identification, early childhood environment, early adolescent experiences, and so on... but no real consensus. IMHO one of the more interesting and credible shrinks that wrote on the question of how "orientation" is formed expressed the belief that it was different for every individual and that various influences had different weights for different people.
Primarily though, I go by life experience and being an observer of human nature for nearly five decades.
The range of human sexual behavior is extremely variable and complex, from what I've seen. You have the example of men in prison (or other situations where there is no sexual access to women) who turn to homosexual behaviors in that circumstance. Many of these men revert to hetero behaviors when females become available (post-release) but some do not.
I've spoken with a number of persons who self-identify as homosexual, who admit nonetheless to occasional sexual encounters with the opposite sex.
You have cross-dressers who are hetero, transgenders who are homosexual, bisexuals, fetishists, and all manner of variations in between. You have people who are solidly het to all appearances who engage in role-reversal sex with the opposite gender.
In short, I believe human sexuality is too complex and variable to simply be explained by the "orientation" theory... especially where the theory assumes orientation is fixed at birth and unchangeable.
Now I WILL grant that habituation can cause a person to favor one version of sex over all others, even to the point where they may become incapable or highly unwilling to have any other kind of sex... this is where something that LOOKS like "orientation" occurs... but they didn't necessarily get there overnight or in a total absence of environmental influences.
The only measure we have of orientation is by observing behavior... but for many humans, sexual behavior can vary a great deal over a long period of time.
I'm just saying I think it is more complicated than the popular hypothesis of orientation can explain.
Do NOT derail this thread with your "theory".
