I have 4... but I've been tattooed more than just 4 times.
I have one on my upper left breast - that was my first one and it needs some assistance now (it's about 18 years old!). It's from Depeche Mode's Violator album - blue rose with D and M on each side. They are still my favourite band (and I met them about 3 weeks after I got the tattoo) so I'm still very happy with it. It's just wee bit faded now.
I had a tattoo gone wrong on my back, so I had a cover up done, but now I hate that tattoo as well... so my brain is churning trying to think of some ideas to give my tattoo artist so he can fix me up.
I had a tribal sun on my left arm. I've changed this into an almost-half-sleeve of beautiful, colourful flowers and the sun is changed a bit into a blue flower. That whole transformation took 5 sessions and 12 hours to complete.
I have the chinese symbol of "friend" on my left ankle. Funnily enough, I got this 3 weeks after I met my boyfriend. We actually went together and got the same tattoo. We were just friends at the time, but we already knew we had a pretty deep connection.
I definitely agree that it's hard to have just one tattoo. I don't think I will stop getting inked for a while and I'm almost 40 years old... I am so amazed by beautiful (and not so! but they are personal choices) ink work that I see and it inspires me to want more
