In my anatomy class we learned that Dopamine is the reason for this they call it "The love chemical"

It is the result of both chemical and physical associative referencing. The chemical gets a bit complicated because it deals with millions of prior physical and mental reference points in a persons life that cause the release of certain combinations of internally  created chemicals at a given point in time. The physical associative referencing is simply dealing with references to prior physical interactions in a persons life. \n\nThese two aspects combine to create our illusion of emotion towards a given event, or in this case, person.\n\nAddition,\nHi Jon, after reading your answer I cant help but ask you two questions based on my belief that it is a choice. \n1. What don't I understand.\n2. Isn't it just a little presumptive to refer to someone that you do not know at all, as rigid in thier mindset?\nThe best thing about this planet is that we can share thoughts and ideas about everything in the hopes of learning, and growing as people. \nIf I believe that sexual preference is a choice, why is that bad. Do you believe that a same sex choice would be a bad one?\nkeeping an open mind

Permanently!!!\n\nYour hair tells your "Health" story.  Scientists can determine what drugs you've taken by reviewing your hair.  Men are attracted to women with long hair because they can determine visually how healthy the woman is by her hair.\n\nThe only way to errase this "Health" record you keep on your head is by shaving off your hair several times.

there sort of are.  hormones are released during puberty, and they start your "sexual awakening".  you become more nterested in romance and sex, and begin getting ready for the reproductive process (ejaculating for guys, menstruating for girls). if you are a guy, you may have wet dreams.  That is normal.  But attraction is just based on your sexual orientation, age, and preferences.  being attracted to someone in particular is all in your mind, not your hormones.  Im not quite sure that last part was accurate, but the first i know was.

I think you mean hermaphrodite. That is an organism (even human, but rarely) that has both male and female sex organs.

One explanation:\n\n"The hormone phenethylamine (PEA) abounds in chocolate, which produces the same sensation as being in love. Chocolates, then, are fuel for both the mental and physical aspects of romance. Small wonder that men offer it to women by the heavy boxful. "

A general answer is Chemicals\nCertain chemicals trigger certain chemicals in your body

Yes, men and women can both be allergic.  It may be the spermicide or some other, non-active ingredient.\n\nI'm allergic to spermacide and it burns terribly!!

Yes annie is right, one of the best substances to reverse this is Grape seed extract, there is a specific formula that is better then pretty much all the other ones but giving the name would be soliciting.

A Harvard study measured chemicals in the brain during the first periods of a relationship and found them to be similar to people diagnosed with mental conditions.  Mine is still going strong (maybe it helps that I'm crazy anyway).

sometimes. It has to do with hormones.

I've also heard of this affect. Males are naturally more aggressive due to their hormones. But when the stimuli related to love are activated, they naturally become more docile, so they're easier to approach and be close to. Humans are still animals regardless of our high opinions of ourselves. Emotions Hormones and pheromones affect us as though they do any other animal. I could see how naturally, with it being in the subconscious that one is married, they're less likely to be aggressive with other males, in order to impress other females. This no longer applies to them, I would suppose it's the same mentality that allows the female gender to let themselves go. Perphaps this is just a scientific study proving that this phenomenon also happens in males. It makes perfect sense.

This is probably your nose telling you the female is genetically compatible to yourself. In human sweat, bacteria produce waste products from protein and hydrocarbon material that was produced by your genetic programming. These waste products still carry information from the genetic code. The adult "nose" and related brain regions have learned to discern compatible notes of sweat from incompatible or too similar notes of sweat, and define a certain range of similarity as attractive.

attractive, attraction, intoxicating would work i guess.  All of those are OK, but intoxicating is best.

it messes with your hormones, so it might

Some of these people seem to be onto the right idea, but are mostly wrong. Pheromones are excreted in your sweat, and are chemicals that are received by our olfactory bulbs (which are responsible for smell). You don't want to maximize the amount of pheromones you excrete unless you're having trouble "getting it up", because in humans, pheromones from a male only affect males, likewise female pheromones. They do exist, and have been "proved", as our grammatically incompetent friend above postulated. So, if you want to improve your chances, you're going to need some lady-sweat. There's evidence for this, too. Have you ever noticed that after physical activity, you feel a little more "in the mood"? Also note that sex is a physical activity which involves sweating... it's all about keeping our species going...

dude your a human being, and your biologically wired to be aroused when you see a member of the opposite sex. So why wouldn't you be aroused when you see them actually performing sex? your human nature is in conflict with your morality. we all go through that. Its a good thing really, otherwise we'd just fuck and eat everything with out thought of the consequences.
