Different forces. They might be there as a pair and get you into heaven or misery. Each strong enough to cause much good or much evil. But mental attraction might last longer beyond the point when physical attraction has faded. Which is probably even more dangerous. Therefore the mental one might be a bit more grave in the end.

Mental for sure, once they get in your mind they are there for life.

for me, mental - pretty girls are a dime a dozen, they fall out of trees downtown

Physical at the start, mental for the long haul.

Its all the same chemical reaction. But I'd say physical attraction is strong where as mental is more of a fungal reaction (it builds and builds)

Mental. Once they are in your head its a maze to get them out.

For me, mental.
