But the mental algorithms whose result outputs as lust don't know that, so they end up making you weak-kneed for some big-breasted wide-hipped woman with a terrible personality.

You know, some of us are "face men" -- men who are turned on (or off) by faces. I literally can't tell if a woman's attractive to me or not unless I can see her face, which makes many popular jokes (e.g. "putting a bag over her head") and supposedly "hot" women incomprehensible to me. Women with mean or vapid faces turn me off no matter what their bodies look like.

(I actually used to be really confused by the notions of "leg man", "breast man", etc. before I found out this other category existed; I couldn't figure out what category I was in. Wish I could remember where I heard about it, though.)
