ORIGINAL: caelestis Well... I think biology can certainly effect how our bodies respond to certain things. For instance, I have cushing's sydrome, which increases the level of my adrenocorticotrophic hormones and in turn, raises the levels of my endorphins. I openly admit that I love the endorphin rushes, I always have, even before I knew what they were. Early in my life it was through exercising, now it is through pain, danger, and arousal. While I've always been a more submissive person, I think I came to this through the allure of pain. I don't think it was really much of a choice for me. Long before I was consciously going after dominant men, I was subconsciously seeking it out in the guys that were around, and it led me to some dangerous situations, because I wasn't being smart about it. At all. Fascinating, have to look at that, never heard of Cushings. There are something like Seven different versions of the DRD4 Dopamine receptor, some of which at least are thought to be associated with risk taking, novelty seeking, and even ADHD - i.e. people not content with doing things the same way everybody else is doing it (which is also a trait of creativity, and creative personalities), and it means some people are more inclined to push the envelope while others prefer to stay tucked safely inside. Nature, hedging her bets as usual, I wouldn't be surprised if at least one of these versions or some arrangement of associated alleles didn't increase sexual adventurousness, it often pays off, in evolutionary terms, and that which works tends to be propagated. Thing is, everybody probably has all Seven copies, or most of the human race, but certain versions are only activated in certain percentages of the population. Heredity might be one of the activators, although specific stressors might activate specific versions as well, so some nature, some nurture, the usual confluence of factors.
