Tattoos

First, so you think I'm not crazy, my boyfriend of 3 years loves tattoos. After waiting for over 2 years for the military (has his physical, so he couldn't get any new ink), he is chomping at the bit to get some tattoos. I don't mind for most of them. He actually asked me to draw him some up - I did one and he is definitely getting it so he says - it is an eagle carrying an anchor that has a snake wrapped up it (kind of a mix of a couple things he wanted - navy, eagle, anchor, and don't tread on me). He seriously LOVED IT. He asked me for some more designs and I'm not sure what else to draw for him. However, the moral of this post is that I'm thinking about asking if he wants to do a couple's tattoo (no names or anything and also something that would make sense without the other just in case) when we get engaged (within the next year he says - the problem for him is getting time off to come home and ask my dad's permission to marry me and to actually do it). For the record, we most likely will not be tying the knot until 2016 ( I need to get my degrees first). But, do you know of any cute military couple tattoos or even just a military guy's tattoo for his woman? I was originally looking for just a guy's and I was gonna pay for it after he proposes...
