A Molecularsexual is someone who has a sexual attraction towards molecules. They most likely would have an attraction towards the “ball and stick” or “van der waals” models. A molecularsexual would probably be attracted to a water molecule model because of the two hydrogen atoms looking like an ass if you look at the van der waals model.
A substance that has two or more atoms chemically bonded together. Examples are H2, H2O, N2, O2, etc. Remember, a molecule is formed by as least two or more ATOMS, so a single oxygen atom (O) is not a molecule.
Sometimes, molecule and compound are very hard to distinguish, for example, H2O (aka water) can be both a molecule AND a compound.
Particles that are brewed from ones feces that are expelled from the anus and become airborne after a fart that may enter an innocent bystander's nose or mouth and ends in a result of ass molecules being comsumed into ones nostrils and lungs getting to know someone's fecal DNA.
