I don't have any and don't plan to. I can just draw on myself with a permanent marker if I feel like having a temporary one.
. Never want anything permanent on my body incase I change my mind lol. I have ear piercings from when I was 2 weeks old. Parents were smart, did it so I couldn't remember it at a young age xD. They used a needle and ice! Wabam!
My my ex had a few... One which included the initials of his first gf... Yes people... Please do not tattoo bf/gf names on your body. Just not a good idea if you plan on dating again after a break up. I never nagged him about it but once in a while it'll just remind me that he's been with other girls etc before me. I always tried to not dwell on it though.
