My wife has worn the queen of spades tats for years, and she has a silver ankle bracelet with a zebra charm on it. The black stripes across that silver charm really show off and have gotten her noticed by the right men more than once. She has heavy 38DD breasts and has considered the idea of an identifying tat on the underside of one of those, because at her age 49, it would be completely hidden unless she lifted a tit to show it, or she was hanging upside down off a bed.lol Four years ago when she got with her current BF he took her, (with no discussion with either of us) to a piercing place. While outside in the car he gripped her between her legs demanding to know if "this" belonged to him. She readily confirmed that it did, and that was when he dropped the bombshell. That since it was his, he was taking her inside to have his ring of ownership put thru one of her lips! Since he is very dominate and she is submissive to him there was really no more discussion, no calling me, nothing. Inside he again gripped her by the twat as he told the woman she was married but this was his so he wanted his ring put in it. The woman took it in stride saying something about "What we do to get their cock!" as she patted my wife's arm and led her behind a curtain telling her to remove her shorts and get up on the table. While observing the procedure her lover told the gal doing it, that my wife could still wear my rings on her finger but that his was now where it mattered. They both had a chuckle over that. After several years of having her lower rings, we would agree with LeatherZebra that this is a much better way to go with a BF, than a tat! Also as someone else said it is a VERY effective spot to attach a leash.
