According to a published study in the International Journal of Medicinal Mushrooms, a certain mushroom found only in specific Hawaiian lava flows can give a woman an instantaneous orgasm upon just smelling the fungus. Yes, this was all researched in the name of science.

 John C. Holliday and Noah Soule, the two scientists involved in this study, found this sexy mushroom in Hawaiian lava flows that were between 600 and 10,000 years old. For the study, the two researchers found female volunteers to take a whiff of the mushroom, which belongs to the Dictyophora species. An astounding more than 50% of the women in the study had an orgasm, right there on the spot! Apparently, the chemical compounds in the mushroom are quite similar to the neurotransmitters in the female brain that are released during sex. 

But unfortunately, males did not have the same response. 0% of males had an orgasm when smelling the same mushroom. They  actually found the smell of the mushroom to be flat-out disgusting.
