Are left hand ring finger rings a for sure sign of being in a relationship?
I would expect to get shot down a lot more often by women wearing rings on their left hands, since many/most of them will be married, engaged, or pretending to be so in order to avoid attentions. But some of them won’t. The question is really how comfortable you are with getting shot down, or occasionally even told off by a pissed-off woman who’s tired of male attention and put on a ring specifically to deter it. So long as you approach courteously, don’t act like a skeezball who’s just out for pussy, and leave politely at the first sign of disinterest, I don’t think anyone would seriously fault your conduct. You can always state more-or-less truthfully that you thought (that is: hoped against all probability) that her ring was just decorative and not a sign of anything.
I wear rings on my left ring finger all the time – because it’s my skinniest finger (other than my pinky, but ugh) and it’s more comfortable to have it on my non-dominant hand (ie The Useless One). It means nothing. If it’s a big sparkley diamond, then it may indicate engagement. But not even then. A good friend of mine bought herself a diamond ring when she got a big promotion at work (not sure which finger she wears it on, though).
i’m another one of those guys who will notice if you have a ring on your left finger. Though I also try and notice the culture of the girl wearing the ring. I’ve known several latinas who received rings from their family for their 15th birthdays who wear their ring on the left hand – ring finger. If the girl is latina and has an engagement style ring but not a wedding band, then she might not be “taken”. But latinas also tend to marry young so when you get to my age, you can never be sure if those rings are from family or from her fiancee/husband/etc. Like phearlez, when I was single, I’d just steer clear of any girl who has a ring on her left hand that could be engagement or wedding style. If it’s a mood ring or something wacky, then it’s 50/50 if I’d make a move. And yes, guys do notice these things just like we notice everything else about a girl that we approach (clothing, hair style, her looks, etc). We just might act like we don’t.
