Personally, being 'yourself'—free from social restraint or influence—is the most attractive quality in any human being, IMHO.
If being yourself involves needing a pointer or two in the most 'prefered' direction, that is totally fine, as well. With that said, I happen to think that rings on a man are extremely, extremely sexy. Granted, it has to be the right man and the right ring. Certain men can look very, very erotic and powerful while rocking the proper ring! If you were to post a photograph of you wearing the clothing that you would wear the ring with, I would be able to give you a more stable yes or no. With what you have informed me of so far though, I would say that confidence is key. Take that into consideration. If you feel as though you would feel like a dweeb wearing it, or you do not know how to integrate it with your overall 'style', then I would say skip the ring. If you feel as though you honestly could pull it off, but were just feeling a bit self-conscious due to how 'foreign' the concept is, I say go for it. Anyone who gives you a hard time for a piece of jewelry is not exactly a gem themselves! Don't let anyone rob you of something you dig! Afterall, this is your life!
