2. A tattoo of his name
The only way this can be acceptable is if you’ve been dating him for over a decade and you know, without a doubt, that you’re going to spend the rest of your lives together. And he has to be as crazy about you as you are about him.
If you aren’t on the exact same wave length, a tattoo will probably freak him out and make you seem obsessive.
Less painful alternative: if you have to put his name on something, put it on a beer glass. If he likes beer (he probably does) this will be a nice, thoughtful gift. If it comes with actual beer, even better.
