Is it normal as a woman to check out guys bulges?

Lately I can't see a guy, from a comfortable distance (maybe 7-10 feet) and not at least glance at his package area to bulge check... I don't know what I'm looking for, but it gives me a rush. Just want to know if other women do this and his do you notice this from women? does anyone think this is the same as guys looking at cleavage or checking out a backside?
