Inexplicable Libido

is it normal for me to be undeniably drawn to people with sub-par standards and lifestyles? and usually working a less-than-blue collar job? (e.g. the guy that works at my parking garage booth...fine, the TWO guys that work at my parking garage booth, the guy on the riding lawn mower that i drove by this morning, etc) obviously, i enjoy the word libido way too much. i'll get over it.
