There was a study done on aromas and their effects. Not as far as like or dislike but actual physiological effects.

The scent that men reacted to the most was;believe it or not; pumpkin. As in the smell of pumpkin pie, baking pumpkin bread, etc. Second was vanilla.

Those two cause more chemical reactions in the body and in the part of the brain that is responsible for sexual arousal in men than any others.

in women it was pumpkin pie, lavendar, baby powder, cucumber, and oddly enough good and plenty. (the candy)
