A ring isn't going to stop an over zealous woman! The married man saying NO is what makes a statement, not a ring.
My husband doesn't wear a ring. He lost it 14 years ago. He has never wore rings and still doesn't and I wasn't wasting our hard earn money replacing it.
I'm confident, comfortable and secure with my marriage and my man. I certainly know that woman are going to approach him whether or not he wears a rings. Because my man is a man of integrity, I trust him to do the right thing. AND because this sister seeks to meet her husband's needs DAILY, I know he don't have time or energy to do nothing but the right thing.
BTW...I wear a wedding ring! However, there was a time when I lost mine and went at least 4 years not wearing one.
