I have a tattoo and plan to get more but I have some things for you to consider.
1. Keep in mind that tattoos are permanent. Things you think are cool might not be so cool on 20 yrs. so choose wisely.
2. Your body changes with age and those changed with effect the look of your tattoos.
3. Tattoos are expensive and can be painful. Be prepared.
4. Do some research before choosing the tattoo artist. There is a big difference in the quality of tattoos available. You will have it forever so spend a few extra bucks for quality.
