Boyfriend's birthday is tomorrow!!

Caitlin • Just here to track my period! Currently dating the love of my life <3
So, I feel like the worlds worst girlfriend because I still haven't gotten him a present. And I don't know what to get him. He is turning 22, but very childish. He's into comics and superheroes but he has PLENTY of that sort of stuff. I told him that he would get birthday sex, so I'll probably go get some sexy lingerie. But I don't know what else. I'm thinking possibly a chain necklace or some nice aftershave or something. Any ideas from you ladies would be wonderful ☺️
