A stomach tattoo is a good place as far as being able to conceal your tattoo when needed is as well as the pain level being fairly low. It is a large part of the body so a more complex tattoo design can be created here. Drawbacks to having a stomach tattoo is that the stomach may change shape in time, for both men and women, as this is where weight gain happens. For women, this is especially true if they plan on having children in the future. Stretch marks and weight gain and stretching of skin can ruin a stomach tattoo.
