| I think that some people have harmones that would cause (for example) a man to think more like a woman then like our normal idea about how men think.
Some direction happens at the comming of age process when people first become interested or knowledgable about sex and different events can shift the direction of what one would prefer.
I some cases it is a matter of choice, because it might be easy to get sex at a gay bar then by dating women, for example, would be a motive for some choices.
So I do not think that one answer covers everyone who gets involved in a same sex relationship |
