DB, I don't know that I'd make a generalization about people who are visually turned on being chasers! Any more than you can say that non-visually stimulated people are duds...!
I am visually stimulated but I can guarantee you that I will never cheat, stray or otherwise betray my spouse. He is mine and I am his. It is VERY hard for me to not look and gawk at other men who I find attractive (thankfully I have a certain "type" that I don't see too often) but I am not a robot; I do have a brain and I am even inclined to use it at times!
Just wanted to point that out....in defense of all of us poor horny visually stimulated people...
