I think with me it's actually pretty balanced. I tend to find people attractive I barely know and I find people attractive I know very well. Both can be pretty inconvenient I have to say ;) One keeps you from getting to know the person better, the other messes up what closeness you already have. I'm not a very successful person when it comes to relationships, seeing as I've never had one, so it probably doesn't matter anyway if I'm attracted before or after I get to know someone ;)

Also I am wearing a thumb ring and it's not cutting off my blood circulation. Plus it looks good even though I don't exactly have thin fingers ;)
