You sure you don't want money instead? I mean, money buys stuff you like, and I really don't pay attention to what people like or dislike or whatever, so I'm a pretty crap gift giver.
Although if I went by what I knew of everyone I've met here, I'd be spending a LOT of dough on sex toys. I don't know what it is about my friends, they just LOVE telling me about their sex lives. You, not so much, but considering who you married, I'm PRETTY SURE I've got a good idea.
