Visited here a fair bit and finally got round to signing up. I'm not sure where to introduce myself but this seems the most sensible area. I'm from the UK and have likely liked this sort of thing since I was 16 I think. I'm not sure I would call it a fetish because I know that part of the point in earrings is decoration, therefore intended to look sexy for a guy.
Anyway all the same, when I see a beautiful girl walk past and she's wearing silver hoops (love them more than any other), something inside me does go off. Generally I like them around 2 inches, 3 inches at best. I just love the way that they swing by her neck as she walks along, or when they turn their head quickly. Same applies to certain types of dangles I suppose. I will admit on the wrong girl they can look fairly trashy, but thats the overall dress sense as opposed to the earrings themselves. However they can also look incredibly classy, which is of course when I like them. I tend to appreciate it when a girl has a good dress sense. Aside from that I also like small pearl studs, tend to look kind of pretty as well.
Where does this fetish come from? I can't say I'm entirely certain, though I do remember noticing it on girls when I was younger. These days if I'm seducing a girl, one thing I love to do is stroke her neck, hair and yes play with one of her earrings. They seem to like it...
