Treat them like normal picture tattoos and fix them on secret spots only your partner can have a peek at. Placing them cheekily on your chest is fine. Why not tantalize and stick them a little lower than this. If on a night out, wear an extremely low cut top or dress which almost makes your assets spill out and then strategically paste a tiny heart or butterfly right down in the middle of your cleavage or your d colletage. On a special night in the bedroom with your partner, place them even lower or on the breasts.
Some men find a woman's hands and feet are some of the sexiest parts of the body.
Affix these at the back of your hands, ankles and even at the hollow of your foot where your joints meet. Do a Christina Aguilera. If you have the time, carefully design intricate patterns all over your belly and expose that tum for that special night out clubbing. If time does not permit, or your wallet does not permit, a simple design around the belly button will serve its purpose. On a night with your guy, place it further down your navel.
