What tattoo should we get?

Hey all. So my husband and I are thinking we want tattoos. This would be our first one for both of us. We both want something small in a not obvious place. My husband isn't a very sentimental guy but he thought of a cute tattoo that was meaningful to both of us we both love that idea. But we also have a fun tattoo we really like, to just remind us to never take life to serious. What's your thoughts sentimental or fun? Also any another tips of tattoos? We want it smaller but I've heard don't go too small (how small is too small?), neither one of us would have a lot of detail no matter which tattoo we choose. Anything helps. Thanks!
