If by sexual excitement, you mean erection (of either the penis or clitoris), the mechanism is nitric oxide. This is why Viagra and similar medications are able to produce their effect (which by the way, should work for women, too.) However, if you mean the pathways of nerve stimulation and arousal, this is located in several nuclei in the brain and involves the hypothalamus, nucleus accumbens, limbic system and cortex among other brain centers.

The biggest sex organ is the Brain, along with hormones. What we consider to be erotic is often dictated by our societal norms, so that people in different cultures are "turned on" by different aspects.
